Interfacing the PCI2040 to the TMS320VC5420 DSP

This application note describes how system designers can interface the TMS320VC5420 16-bit HPI (C5420) to the PCI bus, using the TMS320C6x HPI (C6x) mode interface on the PCI2040 PCI-to-DSP bridge. The note specifies two modes for mapping the C5420 to host memory, depending on the number of C5420s. The note also describes both hardware and software considerations, provides an example schematic, and includes other illustrative figures.
