说明

The TI PCI2040 is a PCI-DSP bridge that 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 PCI2040 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 PCI2040 universal target-only PCI interface is compatible with 3.3-V to 5-V signaling environments.

特性

• Up to four DSP devices on HPI
• Allows direct access to program and control external devices connnected to PCI2040
• Serial ROM interface for loading subsystem ID and subsystem vendor ID
• A 16-bit general-purpose bus (GPB) that provides glueless interface to TI JTAG TBC
• 3.3-V core logic with universal PCI interface compatible with 3.3-V to 5-V signaling environments
• Advanced submicron, low-power CMOS technology
• 144-pin device and choice of surface mount packaging: TQFP or 12 mm x 12 mm MicroStar BGA
• Up to 33 MHz PCI bus frequency
