Engineers at Analog Devices in Wilmington, Mass., needed software for multi-tasking on multiple processors for their ADSP-21060 and ADSP-21062 SHARC digital signal processors (DSPs). The 3L Parallel C product from 3L Ltd. in Edinburgh, Scotland, met their needs.
"Due to SHARC`s extensive multiprocessing capabilities using its six link ports or the external port, over 70 percent of the ADSP-21060 and ADSP-21062 designs are multi-processor," says Len May, the Analog Devices product line marketing manager for SHARC DSPs. "Parallel C can help many SHARC customers get their products to market faster by providing software to enable multiple tasks running on multiple processors with the required intertask communications support."
Parallel C adds two key components to the Analog Devices standard C compiler tools; a distributed, real-time microkernel that supports tasks, threads, timers, and preemptive priority scheduling; and powerful inter-processor message-switching software that provides end-to-end virtual connections over an underlying packet-switched network. Parallel C also improves linker technology in the C compiler itself that eliminates the need for application programmers to manually allocate memory addresses for program sections, and gives the compiler support for ANSI C functions. - J.M.
