Six-core DSPs enable software selection of 3 or 4G air interfaces

摘要

Freescale Semiconductor has announced the next-generation MSC-8157 and MSC8158 programmable, broadband, wireless DSPs. The devices offer more than twice the throughput of their MSC8156 predecessor. The DSPs enable SDR (software-defined radio) for base stations, saving OEMs' development costs with field-upgradable code- and pin-compatible products, which reduce operating expenses for wireless carriers. A software switch lets you use the same DSP for multiple technologies or in a multistandard-mode base station.
