The key features of the DMA coprocessor: D Link pointers that allow DMA channels to auto-initialize D Parallel CPU operation and DMA transfers D 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: D 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 D IEEE floating-point conversion D Division and square-root support D ’C30 assembly language compatibility D Byte and halfword accessibility Key factors in a parallel-processing implementation are the development tools that are available. The ’C40 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: D Optimizing ANSI C compiler with a runtime library that supports use of communication ports and DMA D SPOX, by Spectron Microsystems Incorporated, which provides parallel processing support as well as DMA and communication port drivers D Assembler and linker with support for mapping program and data to parallel processors. SPOX is a trademark of Spectron Microsystems, Inc. |
