Freescale Semiconductor has unveiled its MSC8155 DSP, a higher-performance and cost-optimized version of its flagship MSC8156 DSP based on the latest StarCore technology. The MSC8155 includes next-generation acceleration and interconnect technologies that boost overall chip performance and further enhance the capabilities of broadband wireless base station equipment.

Similar to the MSC8156, the new MSC8155 processor integrates six SC3850 StarCore DSP cores running at 1GHz on a single die, delivering 6GHz of raw DSP performance. The SC3850 core recently earned the best-ever fixed-point BDTImark2000 benchmark score from independent signal-processing technology analysis firm, Berkeley Design Technology Inc.

Major enhancements to the MSC8155 include a second-generation version of Freescale's multi-accelerator platform engine acceleration block (MAPLE-B2L) and the newest interconnect Serial RapidIO Gen2 technology. The MSC8155 DSP supports existing 3G-UMTS, TD-SCDMA and WiMAX base station deployments and upcoming 3G-LTE standards such as FDD-LTE and TDD-LTE features including Turbo/Viterbi FEC.

"The MSC8155 DSP brings even greater functionality and higher system performance to baseband and industrial applications," said Scott Aylor, general manager of DSP products for Freescale's networking and multimedia group. "Building on the innovation and market traction of the MSC8156 device, the enhanced MSC8155 offers OEMs the scalability and connectivity they need for their common base station platforms."

The new DSP is designed to help OEMs take full advantage of 3G-LTE, HSPA+ and WiMAX at very high throughput required for the most advanced 20MHz 3G-LTE and HSPA+ base stations. The raw performance of the fully programmable cores and the MAPLE-B2L acceleration technology also eliminate the need to incorporate costly FPGAs or develop ASIC devices for 3G-LTE and WiMAX base stations.

"The MSC8155 continues Freescale's demonstrated expertise in delivering DSP devices that support multiple standards to meet the base station requirements of today and tomorrow," said Will Strauss, president of Forward Concepts, a leading analyst firm tracking DSP technologies. "The flexibility of Freescale's enhanced MAPLE technology, together with the high performance of Freescale's StarCore technology, should prove appealing to OEMs looking to keep up with carrier and consumer demand for ever more bandwidth as smart mobile devices advance and the number of Internet users worldwide continues to explode."
