| Abstract: | TMS320C6455 is a kind of high-performance fixed-point Digital Signal Processing（DSP）, which integrates various peripherals. This paper firstly introduces the features of the Peripheral Component Interconnect（PCI） interface controller, the way to communicate with other modules in DSP and the address mapping of slave/master work mode. Then bus transfer characteristics and performance of two work modes is analyzed in detail and the application of its PCI interface controller on satellites baseband signal receiver is also given. TMS320C6455’s PCI interface controller can simplify the hardware design, and have the characteristics of flexible and efficient, therefore it has good application prospects in engineering practice. |
