Abstract :
We present performance analysis results of the MSP500 digital baseband (DBB) platform, a system developed at Analog Devices Inc., targeted at cellular handsets supporting the GSM, GPRS, and EDGE communication standards. We focus on a particular member of the MSP500 family, the AD6532 device, which integrates a Blackfin® core, and examine the execution time performance of a number of wireless physical layer software components from the perspective of an instruction- and data-cached memory hierarchy. The Blackfin is a 16-bit fixed-point core that combines some of the best features of DSPs and micro-controllers, and has support for a cached memory system.
