IDT公司日前推出用于数字信号处理器(DSP)集群的预处理交换(PPS,pre-processing switch)芯片,IDT流量控制管理部高级产品经理Bill Beane说,PPS芯片是专为无线基带处理应用设计,采用串行RapidIO(sRIO)互连,集成了一套创新字节级和信息包级处理能力,用来卸载特定带宽密集任务DSP的负担。这种卸载可使集群内DSP的性能提高20%,从而有助于处理器集中于其他计算密集的功能,以满足下一代无线基础设施的设计要求。
IDT Corp. has introduced a PPS (pre-processing switch) chip for digital signal processor (DSP) clusters and Bill Beane, senior product manager for IDT Traffic Control Management, said the PPS chip is designed for wireless baseband processing applications , A Serial RapidIO (sRIO) interconnect that incorporates a set of innovative byte and packet-level processing capabilities to offload the bandwidth-intensive mission-specific DSPs. This uninstallation increases DSP performance in the cluster by up to 20 percent, helping processors to focus on other compute-intensive features to meet the design requirements of the next generation of wireless infrastructure.
