How do you apply DSPs, micro-controllers, FPGA, Counters, Timers and FIFI in the CPCC unit?

Under the CPCC platform we are applying an advanced digital design. In our electronic module we are using DSP - Digital Signal processors usual Texas Instruments based and various micro-controllers including 8051 family. To run this smoothly we use different types memories, buffers, CPLD, FPGA. Our digital design contains many different digital circuits including busses, buffers, counters and timers run on 400Mhz. 01
