6 Detailed Description

6.1 CPU

The fixed-point digital signal processors (DSP) are based on the C55x CPU 3.3 generation processor core. The C55x DSP architecture achieves high performance and low power through increased parallelism and total focus on power savings. The CPU supports an internal bus structure that is composed of one program bus, three data read buses (one 32-bit data read bus and two 16-bit data read buses), two 16-bit data write buses, and additional buses dedicated to peripheral and DMA activity. These buses provide the ability to perform up to four data reads and two data writes in a single cycle. Each DMA controller can perform one 32-bit data transfer per cycle, in parallel and independent of the CPU activity.

The C55x CPU provides two multiply-accumulate (MAC) units, each capable of 17-bit x 17-bit multiplication in a single cycle. A central 40-bit arithmetic and logic unit (ALU) is supported by an additional 16-bit ALU. Use of the ALUs is under instruction set control, providing the ability to optimize parallel activity and power consumption. These resources are managed in the Address Unit (AU) and Data Unit (DU) of the C55x CPU.

The C55x DSP generation supports a variable byte width instruction set for improved code density. The Instruction Unit (IU) performs 32-bit program fetches from internal or external memory, stores them in a 128-byte Instruction Buffer Queue, and queues instructions for the Program Unit (PU). The Program Unit decodes the instructions, directs tasks to AU and DU resources, and manages the fully protected pipeline. Predictive branching capability avoids pipeline flushes on execution of conditional instruction calls.

For more detailed information on the CPU, see the TMS320C55x CPU 3.0 CPU Reference Guide (literature number SWPU073).

6.2 Memory

6.2.1 Internal Memory

6.2.1.1 On-Chip Dual-Access RAM (DARAM)

The DARAM is located in the byte address range 000000h − 00FFFFh and is composed of eight blocks of 4K words each (see Table 6-1). Each DARAM block can perform two accesses per cycle (two reads, two writes, or a read and a write). The DARAM can be accessed by the internal program, data, or DMA buses.

Table 6-1 DARAM Blocks

CPU
BYTE ADDRESS RANGE		 DMA CONTROLLER
BYTE ADDRESS RANGE		 MEMORY BLOCK
000000h – 001FFFh 0001 0000h – 0001 1FFFh DARAM 0(1)
002000h – 003FFFh 0001 2000h – 0001 3FFFh DARAM 1
004000h – 005FFFh 0001 4000h – 0001 5FFFh DARAM 2
006000h – 007FFFh 0001 6000h – 0001 7FFFh DARAM 3
008000h – 009FFFh 0001 8000h – 0001 9FFFh DARAM 4
00A000h – 00BFFFh 0001 A000h – 0001 BFFFh DARAM 5
00C000h – 00DFFFh 0001 C000h – 0001 DFFFh DARAM 6
00E000h – 00FFFFh 0001 E000h – 0001 FFFFh DARAM 7
(1) The first 192 bytes are reserved for memory-mapped registers (MMRs). See Section 6.2.2, Memory Map Summary.

6.2.1.2 On-Chip Read-Only Memory (ROM)

The zero-wait-state ROM is located at the byte address range FE0000h – FFFFFFh. The ROM is composed of four 16K-word blocks, for a total of 128K bytes of ROM. The ROM address space can be mapped by software to the internal ROM.

The standard device includes a bootloader program resident in the ROM.

When the MPNMC bit field of the ST3 status register is cleared (by default), the byte address range FE0000h – FFFFFFh is reserved for the on-chip ROM. When the MPNMC bit field of the ST3 status register is set through software, the on-chip ROM is disabled and not present in the memory map, and byte address range FE0000h – FFFFFFh is unmapped. A hardware reset always clears the MPNMC bit, so it is not possible to disable the ROM at reset. However, the software reset instruction does not affect the MPNMC bit. The ROM can be accessed by the program and data buses. Each on-chip ROM block is a one cycle per word access memory.

6.2.1.3 On-Chip Single-Access RAM (SARAM)

Section 6.2.1.3.1 explains the SARAM blocks for the C5535. Section 6.2.1.3.2 explains the SARAM blocks for the C5534. Section 6.2.1.3.3 explains the SARAM blocks for the C5533. The C5532 has no SARAM blocks.

6.2.1.3.1 SARAM for C5535

The SARAM is located at the byte address range 010000h – 04FFFFh and is composed of 32 blocks of 4K words each (see Table 6-2). Each SARAM block can perform one access per cycle (one read or one write). SARAM can be accessed by the internal program, data, or DMA buses.

SARAM is also accessed by the USB and LCD DMA buses.

6.2.1.4 I/O Memory

Each device includes a 64K byte I/O space for the memory-mapped registers of the DSP peripherals and system registers used for idle control, status monitoring and system configuration. I/O space is separate from program and memory space and is accessed with separate instruction opcodes or via the DMAs.

Table 6-5, Table 6-6 and Table 6-7 list the memory-mapped registers of each device. Note that not all addresses in the 64K byte I/O space are used; these addresses must be treated as reserved and not accessed by the CPU nor DMA. For the expanded tables of each peripheral, see , Peripheral Information and Electrical Specifications of this document.

Some DMA controllers have access to the I/O-Space memory-mapped registers of the following peripherals registers: I2C, UART, I2S, SD, USB, and SAR ADC.

Before accessing any peripheral memory-mapped register, make sure the peripheral being accessed is not held in reset via the Peripheral Reset Control Register (PRCR) and its internal clock is enabled via the Peripheral Clock Gating Control Registers (PCGCR1 and PCGCR2).

6.4 Boot Modes

The DSP supports the following boot modes in the following device order: SPI 16-bit EEPROM, SPI 24-bit Flash, I2C EEPROM, and eMMC boot partition, eMMC, SD, or SDHC card. The boot mode is determined by checking for a valid boot signature on each supported boot device. The first boot device with a valid boot signature will be used to load and execute the user code. If none of the supported boot devices have a valid boot signature, the bootloader goes into an endless loop checking the UART or USB boot mode and the device must be reset to search for another valid boot image in the supported boot modes.

Note: For detailed information on eMMC boot partition, eMMC, SD, or SDHC and UART or USB boot modes, contact your local sales representative.

6.4.1 Invocation Sequence

The boot sequence is a process by which the device's on-chip memory is loaded with program and data sections from an external image file (in flash memory, for example). The boot sequence also allows, optionally, for some of the device's internal registers to be programmed with predetermined values. The boot sequence is started automatically after each device reset. For more details on device reset, see Section 5.7.3, Reset.

There are several methods by which the memory and register initialization can take place. Each of these methods is referred to as a boot mode. At reset, the device cycles through different boot modes until an image is found with a valid boot signature. The on-chip bootloader allows the DSP registers to be configured during the boot process, if the optional register configuration section is present in the boot image (see Figure 6-6). For more information on the boot modes supported, see Section 6.4, Boot Modes.

The device bootloader follows the following steps as shown in Figure 6-6

  1. Immediately after reset, the CPU fetches the reset vector from 0xFFFF00. MP or MC is 0 by default, so 0xFFFF00 is mapped to internal ROM. The PLL is in bypass mode.
  2. Set CLKOUT slew rate control to slow slew rate.
  3. Idle all peripherals, MPORT and HWA.
  4. If CLK_SEL = 0, the bootloader powers up the PLL and sets its output frequency to 12.288 MHz (with a 375x multiplier using VP = 749, VS = 0, input divider disabled, output divide-by-8 enabled, and output divider enabled with VO = 0). If CLK_SEL = 1, the bootloader keeps the PLL bypassed. Enable Timer0 to count the settling time of BG_CAP.
  5. Apply manufacturing trim to the bandgap references.
  6. Disable CLKOUT.
  7. Test for 16-bit and 24-bit SPI EEPROM boot on SPI_CS[0] with a 500-kHz clock rate and set to Parallel Port Mode on the External Bus Selection Register to 5, then set to 6:
    1. Check the first 2 bytes read from boot table for a boot signature match using 16-bit address mode.
    2. If the boot signature is not valid, read the first 2 bytes again using 24-bit address mode.
    3. If the boot signature is not valid from either case (16-bit and 24-bit address modes), go to step 8.
    4. Set Register Configuration, if present in boot image.
    5. Attempt SPI Serial Memory boot, go to step 12.
  8. Test for I2C EEPROM boot with a 7-bit slave address 0x50 and 400-kHz clock rate.
    1. Check the first 2 bytes read from boot table for a boot signature match.
    2. If the boot signature is not valid, go to step 9.
    3. Set Register Configuration, if present in boot image.
    4. Attempt I2C EEPROM boot, go to step 12.
  9. Test for eMMC partitions, eMMC, SD0 boot:
    • For an eMMC, SD, or SDHC card, the card must be formatted to FAT16 or FAT32. The boot image file must be renamed to "bootimg.bin" and copied to the foot directory of the formatted card.
    • If an eMMC boot partition is desired (for only eMMC 4.3 and up), then the boot image file must be programmed to one of the two boot partitions (1 or 2) on the eMMC card. PARTITION_CONFIG in the EXT_CSD must be set accordingly.
    • If the boot signature is found, attempt eMMC, SD, or SDHC boot and go to step 12.
      If boot signature is not found, go to step 10.
  10. Set the PLL output to approximately 36 MHz. If CLK_SEL = 1, CLKIN multiplied by 3x. If CLK_SEL = 0, CLKIN is multiplied by 1125x. Re-enable TIMER0 to start counting the settling time of BG_CAP due to the PLL change.
  11. Test for UART or USB1 boot:
    • The USB internal LDO will be enabled and the device is configured to accept a boot image on EP1 OUT.
    • UART will be set to 57600 baud, 8 bit, 1 stop bit, CTS or RTS auto flow control, and odd parity will be enabled to accept a boot image from the UART transmitter.
    • The device will poll UART and USB in turns. If a valid boot signature is detected on either device, a boot image will attempt to download on that device. Go to step 12.
      If a valid signature is not detected, return to the start of this step.
  12. Copy the boot image sections to system memory.
  13. Ensure a minimum of 200 ms has elapsed before proceeding to execute the bootloaded code.
  14. Jump to the entry point specified in the boot image.

Figure 6-6 Bootloader Software Architecture

6.4.2 Boot Configuration

After reset, the on-chip bootloader programs the system clock generator based on the input clock selected via the CLK_SEL pin. If CLK_SEL = 0, the bootloader programs the system clock generator and sets the system clock to 12.288 MHz (multiply the 32.768-kHz RTC oscillator clock by 375). If CLK_SEL = 1, the bootloader bypasses the system clock generator altogether and the system clock is driven by the CLKIN pin.

Note:

  • When CLK_SEL =1, the CLKIN frequency is expected to be 11.2896 MHz, 12.0 MHz, or 12.288 MHz.
  • The on-chip bootloader allows for DSP registers to be configured during the boot process. However, this feature must not be used to change the output frequency of the system clock generator during the boot process. Timer0 is also used by the bootloader to allow for 200 ms of BG_CAP settling time. The bootloader register modification feature must not modify the PLL or Timer0 registers.

After hardware reset, the DSP boots via the bootloader code in ROM. During the boot process, the bootloader queries each peripheral to determine if it can boot from that peripheral. At that time, the individual peripheral clocks will be enabled for the query and then disabled when the bootloader is finished with the peripheral. By the time the bootloader releases control to the user code, all peripheral clocks will be "off" and all domains in the ICR, except the CPU domain, will be idled.

6.4.3 DSP Resources Used By the Bootloader

The bootloader uses SARAM block 31 for the storing of temporary data. This block of memory is reserved during the boot process. However, after the boot process is complete, it can be used by the user application.
