    DSP Reference Guides
    SPRUG82TMS320C674x DSP Cache User's Guide. Explains the fundamentals of memory caches and describes how the two-level cache-based internal memory architecture in the TMS320C674x digital signal processor (DSP) can be efficiently used in DSP applications. Shows how to maintain coherence with external memory, how to use DMA to reduce memory latencies, and how to optimize your code to improve cache efficiency. The internal memory architecture in the C674x DSP is organized in a two-level hierarchy consisting of a dedicated program cache (L1P) and a dedicated data cache (L1D) on the first level. Accesses by the CPU to the these first level caches can complete without CPU pipeline stalls. If the data requested by the CPU is not contained in cache, it is fetched from the next lower memory level, L2 or external memory.
    SPRUFE8TMS320C674x DSP CPU and Instruction Set Reference Guide. Describes the CPU architecture, pipeline, instruction set, and interrupts for the TMS320C674x digital signal processors (DSPs). The C674x DSP is an enhancement of the C64x+ and C67x+ DSPs with added functionality and an expanded instruction set.
    SPRU186TMS320C6000 Assembly Language Tools User's Guide. Describes the assembly language tools (assembler, linker, and other tools used to develop assembly language code), assembler directives, macros, common object file format, and symbolic debugging directives for the TMS320C6000 platform of devices (including the C64x+, C67x+, and C674x generations).
    SPRU187TMS320C6000 Optimizing Compiler User's Guide. Describes the TMS320C6000 C compiler and the assembly optimizer. This C compiler accepts ANSI standard C source code and produces assembly language source code for the TMS320C6000 platform of devices (including the C64x+, C67x+, and C674x generations). The assembly optimizer helps you optimize your assembly code.
    SPRUH90TMS320C6743 DSP Technical Reference Manual. Describes the System-on-Chip (SoC) and each peripheral in the device.
    SPRUFK5TMS320C674x DSP Megamodule Reference Guide. Describes the TMS320C674x digital signal processor (DSP) megamodule. Included is a discussion on the internal direct memory access (IDMA) controller, the interrupt controller, the power-down controller, memory protection, bandwidth management, and the memory and cache.
    SPRUFK9TMS320C674x/OMAP-L1x Processor Peripherals Overview Reference Guide. Provides an overview and briefly describes the peripherals available on TMS320C6743.
