The TMS320VC5470 integrates a DSP subsystem based on the TMS320C54x architecture and a RISC microcontroller subsystem based on the ARM7TDMI core as shown in Figure 2-1. The DSP subsystem includes 72K x 16-bit SRAM, a timer, a DMA controller, an external memory interface, and two McBSPs. The MCU subsystem includes three timers, general-purpose I/O, and an external memory interface.

The TMS320VC5470 is implemented as two major subsystems that are highly independent. The DSP subsystem includes the following modules:

  • TMS320C54x™ DSP core
  • 72K x 16-bit internal SRAM organized as 32K x 16-bit of data SRAM and 40K x 16-bit of program SRAM.
  • ARM port interface (API) to provide access by the MCU to 8K x 16 of the DSP’s data SRAM
  • Two multichannel buffered serial ports (McBSPs)
  • Phase-locked loop (PLL)
  • Timer
  • Direct memory access (DMA) controller
  • Programmable wait-state generator
  • External memory interface
