The TMP/ SMJ320C40KGD DSP is a 32-bit, floating-point processor manufactured in 0.72-um, double-level metal CMOS technology. It is the fourth generation of DSPs from Texas Instruments, and it is the world\x92s first DSP designed for parallel processing. The on-chip parallel processing capabilities of the \x92C40 make the floating-point performance required by many applications achievable and cost-effective.

The TMP/ SMJ320C40 is the first DSP with on-chip communication ports for processor-to-processor communication using simple communication software with no external hardware. This allows connectivity with no external glue logic. The communication ports remove I/O bottlenecks, and the independent smart-DMA coprocessor is able to handle the CPU I/O requirements.

The features of the communication ports are:

• Six communication ports for direct interprocessor communication and processor I/O
• 20 MBps bidirectional interface on each communication port for high-speed and low-cost multiprocessor interface
• Separate input and output first-in, first-out (FIFO) buffers for I/ O and processor-to-processor communication
• Automatic arbitration and handshaking for direct processor-to-processor connection

The DMA coprocessor allows concurrent I/O and CPU processing for superior sustained CPU performance.
The key features of the DMA coprocessor:

• Link pointers that allow DMA channels to auto-initialize
• Parallel CPU operation and DMA transfers
• Six DMA channels support communication-port-to-memory data transfers

The TMP/SMJ320C40KGD CPU is configured for high-speed internal parallel processing. The key features of the CPU are:

• Eight operations/ cycles
  • 40-/ 32-bit floating-point / integer multiply
  • 40-/32-bit floating-point/ integer arithmetic and logic unit (ALU) operation
  • Two data accesses
  • Two address-register updates
• IEEE floating-point conversion
• Division and square-root support
• \x92C30 assembly language compatibility
• Byte and halfword accessibility

Key factors in a parallel-processing implementation are the development tools that are available. The \x92C40 is supported by a host of parallel-processing development tools for developing and simulating code and for debugging parallel-processing systems. The code generation tools include:

• Optimizing ANSI C compiler with a runtime library that supports use of communication ports and DMA
• SPOX™, by Spectron Microsystems Incorporated, which provides parallel processing support as well as DMA and communication port drivers
• Assembler and linker with support for mapping program and data to parallel processors.

The simulation tools include:

• Parallel DSP system-level simulation, by Logic Modeling Corporation (LMC), which includes a hardware verification (HV) model and a full functional (FF) model
• TI software simulator with high-level language debugger interface for simulating a single processor

The hardware development and verification tools include:

• Parallel processor in-circuit emulator and high-level language debugger: XDS510™
• Parallel processor development system with four TMS320C40s, local and global memory, and communication port connections
