ARM Cortex-A5
The ARM Cortex-A5 is a 32-bit processor core licensed by ARM Holdings implementing the ARMv7-A architecture announced in 2009.
Overview
The Cortex-A5 is intended to replace the ARM9 and ARM11 cores for use in low-end devices. The Cortex-A5 offers features of the ARMv7 architecture focusing on internet applications e.g. VFPv4 and NEON advanced SIMD.Key features of the Cortex-A5 core are:
- Single-issue, in-order microarchitecture with an 8-stage pipeline
- NEON SIMD instruction set extension
- VFPv4 floating-point unit
- Thumb-2 instruction set encoding
- Jazelle RCT
- 1.57 DMIPS / MHz
