FreescaleªºMSC8144 DSP ´£ª@Ävª§¯à¤O (­^¤å¤º®e)

Freescale's MSC81xx DSP, which is based on the SC3400 core from StarCore, achieved a BDTIsimMark2000 speed score ranging from 9520 - 11900, using only one of its four SC3400 cores. This result confirms that the MSC8144 DSP offers greater signal-processing speed than Texas Instruments' TMS320C64x+ based device.



"Freescale is committed to StarCore DSP technology," said Jeff Timbs, director of marketing for Freescale's Digital Systems Division. "Marketplace demand for DSP technologies that provide channel density and support video collaboration applications requires an industry leading core. The outstanding benchmark results generated by the SC3400 provide an independent indication of the processing speed underlying the engine used in our MSC8144 DSP."



The MSC8144 is Freescale's third generation multicore DSP, and the first to be based on the SC3400 architecture. The BDTI numbers demonstrate the significant performance gain that Freescale has achieved using the advanced SC3400 core architecture based on StarCore technology. Freescale's implementation of the SC3400 offers a performance increase nearly double the StarCore based SC140 core currently used in Freescale's MSC8102 and MSC8122/26 multicore DSPs.



BDTI specializes in independent analysis of DSP technology. The BDTIsimMark2000 is a summary measure of a processors' signal-processing speed. The score is distilled from a processor's results on the BDTI DSP Kernel Benchmarks, a suite of 12 key DSP algorithms. A higher score indicates a faster processor. The 12 key DSP algorithms include FIR, IIR, Vector manipulation, Viterbi, FFT, Bit unpack and control code. These kernels are the building blocks for wireless, wireline and video infrastructure systems that Freescale's MSC8144 DSP enables.
