The communication between TMS320C54x DSP and CPLD through host port interface

摘要

The communication problem is critical in an optimized design of adopting Complex Programmable Logic Device (CPLD) to realize the control functions and DSP to achieve the data processing. The principle of TMS320C54x's host port interface was first introduced. Then, the implementation method of communication between DSP and CPLD was elaborated upon. Systems adopting this method have the advantages of simple interface and high transmission speed, without affecting the data processing of the DSP.
