P5020NSE1VNB数据手册恩XP中文资料规格书

描述 Description

The dual-core P5020 and single-core P5010 processors deliver 64-bit processing, based on the e5500 core built on Power Architecture® technology. With frequencies scalable to 2.0 GHz, large caches and high per-cycle efficiency, these products target control plane and computer applications that require high single-threaded performance.
The P5 platform leverages architectural features pioneered in the P4 platform, including the three-level cache hierarchy for low latencies, hardware hypervisor for robust virtualization support, data path acceleration architecture (DPAA) for offloading packet handling tasks from the core and the CoreNet® switch fabric that eliminates internal bottlenecks. This enables architectural compatibility from the P5 platform to the P4 platform as well as to the P3 platform.
