TMS320C67x DSP Architecture
1-7IntroductionSPRU733
1.4 TMS320C67x DSP Architecture
Figure 11 is the block diagram for the C67x DSP. The C6000 devices come
with program memory, which, on some devices, can be used as a program
cache. The devices also have varying sizes of data memory. Peripherals such
as a direct memory access (DMA) controller, power-down logic, and external
memory interface (EMIF) usually come with the CPU, while peripherals such
as serial ports and host ports are on only certain devices. Check the data sheet
for your device to determine the specific peripheral configurations you have.
