Bangalore: Freescale Semiconductor has introduced its MSC8155 digital signal processor (DSP), the latest version of the company's flagship MSC8156 DSP based on the latest StarCore technology. According to Freescale, 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. 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.
"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," said Scott Aylor, General Manager of DSP products for Freescale's Networking and Multimedia Group. The MSC8156 DSP has been qualified on advanced 45-nanometer process technology and is now ramping into production. Freescale plans to sample the new MSC8155 device to select customers in third quarter of 2010. The MSC8155 is housed in a 783-pin FC-PBGA package.
The new DSP is designed to help original equipment manufacturers 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.
