Abstract

This paper investigates hardware/software implementation tradeoffs in the reassembly of cells for IP-over-ATM on an integrated architecture combiningprocessing, memory, and embedded direct-memory-access (DMA) engines for the sources and sinks of communication traffic. Two approaches are considered. In the first approach, CRC computation is performed in software. In the second approach, CRC computation is of loaded to a specialized module embedded in one of the DMA engines. The two alternatives are evaluated through simulated execution of representative control software with detailed modelingof cache/memory effects and bus contention. The results indicate that the software CRC approach can support OC-3 rates with a 333 MHz processor, and the hardware CRC approach can support OC-3 rates with a 71 MHz processor and OC-12 rates with a 333 MHz processor.
