description (continued)
The features of the communication ports are:
Six communication ports for direct interprocessor communication and processor I/O
20M-byte/s 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 processor-to-processor communication and
I/O
Automatic arbitration and handshaking for direct processor-to-processor connection
The DMA coprocessor allows concurrent I/O and CPU processing for the highest 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 parallelism for the highest sustained
performance. The key features of the CPU are:
Eight operations/cycle
–
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
’C30 assembly language compatibility
Byte and halfword accessibility
A key factor in a parallel-processing implementation is the development tools available. The ’C40 is supported
by a host of parallel-processing development tools for developing and simulating code easily 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 full functional (FF) model
TI software simulator with high-level language debugger interface for simulating a single processor
