Communication signal processing module that is the core of the high performance, low power consumption,
16 bit fixed-point digital signal processor (DSP) chip - MS320VC5509A is produced by TI company. DSP
chip in the system main completes coding and decoding of OFDM, CODEC control and data signal flow
transmission.TMS320VC5509A provides three high-speed, full duplex, multi-channel buffer serial port - McBSP, each
serial interface can support 128 channels, at speeds of up to 100 Mb/s. Multi-channel buffer serial port
(McBSP) can provides a direct serial port in TMS320VC5509A DSP or between DSP and other devices of
system. It is feasible that DSP can directly connect with other C55xx DSP, CODEC of industrial standard port,
and other serial (ADC/DAC) devices of system. Different McBSP of DSP number and the pin number is also
different.
