Overview
editThe Cortex-A5 is intended to replace theARM9andARM11cores for use in low-end devices.[1]The Cortex-A5 offers features of the ARMv7 architecture focusing on internet applications e.g. VFPv4 and NEON advanced SIMD.[2]
Key features of the Cortex-A5 core are:
- Single-issue,in-ordermicroarchitecture with an 8-stagepipeline[1]
- NEONSIMDinstruction set extension (optional)
- VFPv4floating-point unit(optional)
- Thumb-2instruction set encoding
- Jazelle RCT
- 1.57DMIPS/ MHz
