Abstract :
A 90 nm ARM™ V5TE compatible microprocessor core intended for high performance and low power embedded applications is described. The core includes an ECC protected 2 level 512 MB cache, high-bandwidth single-cycle L1 cache line fill and evict, and cache coherency. Circuit design for high speed and low power are described, as well as their impact on the micro-architecture. Features to support low standby power modes and embedded test are also described.
