TMS320C40 Parallel Processing Development System (PPDS)

The TMS320C40 Parallel Processing Development System(PPDS) is the first development board designed exclusively to evaluate and develop parallel-processing, floating-point software applications. You can develop, benchmark, and evaluate code in real-time in a rich development environment with the power and speed of the TMS320C40 PPDS.

The C4x PPDS is a stand-alone C4x target system (with power supply) that is placed on the desktop and is controlled through an emulator, available separately. The board has 4 TMS320C40 DSPs, 64K x 32-bit words of local SRAM, 8K bytes of EPROM, and 128K x 32-bit workds of shared global SRAM. The board can be used with the C4x PC XDS510 emulator (OS/2) or the C4x SPARC XDS510WS emulator (OpenWindows).

Each TMS320C40 on the PPDS has direct connections to each of the other TMS320C40s in the system through the communication ports, allowing the user to experiment with various topologies that are best suited for an application.

These features and more give the user the flexibility to distribute tasks between multiple processors and to develop, benchmark, and debug multiprocessing algorithms.

Key features of the PPDS include:

Four on-board 32MHz TMS320C40 parallel processors. Each TMS320C40 is supported by a local bus consisting of:
- 64K x 32-bit words of zero wait-state static RAM (SRAM)
- 8K bytes of EPROM
128K x 32-bit words of one wait-state SRAM on a shared global bus
An expansion bus connector that provides an external interface to the shared global memory bus, interrupt pins, and timer pins.
Eight external communication port connectors that provide an interface for connecting off-board TMS320C40s and external peripherals to the communication ports of the on-board 'C40s.
An IEEE Std 1149.1-1990-compliant(JTAG) test connector that serves as an interface for connecting the PC XDS510 or SPARC XDS510WS scan-based emulator.
