PCI2040PGE

Product Summary

The PCI2040PGE is a PCI-DSP Bridge Controller. It provides a glueless connection between the 8-bit host port interface (HPI) port on the TMS320C54X or the 16-bit HPI port on TMS320C6X to the high performance PCI bus. It provides a PCI bus target interface compliant with the PCI Local Bus Specification. The PCI2040PGE provides several external interfaces: the PCI bus interface with compact PCI support, the HPI port interface with support for up to four DSPs, a serial ROM interface, a general-purpose input/output interface (GPIOs), and a 16-bit general-purpose bus to provide a glueless interface to TI JTAG test bus controller (TBC). The PCI2040PGE also provides a serial ROM interface for preloading several registers including the subsystem ID and subsystem vendor ID.
