ADVANCE INFORMATION
At a high level there is one customer programmable subsystem. The left hand side shows TI's high performance HWA 1.5, a high-bandwidth interconnect for high performance (128-bit, 150 MHz), and associated peripherals – LVDS interface for Measurement data output, L3 Radar data cube memory, ADC buffers, CRC engine, and data handshake memory (additional memory provided on interconnect).
The right side of the diagram shows the Main subsystem (MSS). The Main subsystem, as the name suggests, is the primary controller of the device and controls all the device peripherals and house-keeping activities of the device. The Main subsystem contains a Cortex-R5F (MSS R5F) processor and associated peripherals and housekeeping components such as EDMAs, CRC, and peripherals (I2C, UART, SPI, EPWM, and others) connected to the primary interconnect through the Peripheral Central Resource (PCR interconnect).
The Radio Processing Subsystem or the BIST Subsystem (RSS) is responsible for initializing and calibrating the Analog/RF modules. RSS periodically monitors the Analog/RF functionality such that all the Analog/RF modules work in their defined limits.
General-Purpose ADC (GPADC), Fast Fourier Transformation engine (FFT engine) and other modules are provided to monitor the signal from different points in the transmitter and receiver chains. Digital front-end filters (DFE), Ramp Generation module and Analog/DFE registers, which are mainly under the control of BSS, can be indirectly controlled through the API calls from the Main Subsystem.
