Interfacing theTMS320C6000 EMIFto a PCI Bus Using the AMCC S5933 PCI Controller (Rev. A)

This application report describes the architecture and capabilities of the AMCC S5933 PCI controller and how it can be interfaced to the TMS320C6201 digital signal processor (DSP). The DSP's host port interface (HPI) can be a PCI target, and its external memory interface (EMIF) can be used to support PCI bus mastering. Details on the signals and logic required to implement both PCI slave and master interfaces with the TMS320C6201 DSP are presented. Modifications to the design that allow other TMS320C6000™ series processors in place of the TMS320C6201 are presented. Suggestions are provided on how to improve on the design to achieve greater data throughput.
