• ARM Cortex-R family: • Real-time processors with high performance and high reliability. • Support real-time processing and mission-critical control. The A8 processor is the first 64-bit ARM based SoC. It supports ARM A64, A32, and T32 instruction set.
The ARM Cortex-A8 is a 32-bit processor core licensed by ARM Holdings implementing the ARMv7-A architecture. Compared to the ARM11, the Cortex-A8 is a dual-issue superscalar design, achieving roughly twice the instructions per cycle.
Although ARM announces products year-round, they always have a couple of announcements reserved for TechCon and this year is no exception. Being unveiled at 2015’s show is the ARM Cortex-A35 CPU and the ARMv8-M instruction set architecture, the latter being the focus of this article. As a brief bit
Cortex-A8/R4/M3/M1 Thumb-2 Extensions: v7A (applications) – NEON v7R (real time) – HW Divide V7M (microcontroller) – HW Divide and Thumb-2 § Latest ARM cores introduce a new instruction set Thumb-2. § Provides a mixture of 32-bit and 16-bit instructions § Maintains code density with
ARM Cortex-M Assembly Instructions. NOTE: Ra Rd Rm Rn Rt represent 32-bit registers. value any 32-bit value: signed, unsigned, or address {S} if S is present, instruction will set condition codes #im12 any value from 0 to 4095 #im16 any value from 0 to 65535 {Rd,} if Rd is present Rd is destination
Linaro GCC 4.9 Toolchain optimized for Cortex-A8 cpu. This repo contains latest Linaro GCC 4.9 toolchain optimized for Cortex-A8 cpu with Neon-VFPv3 technology support (like Qualcomm Snapdragon Scorpion cpu mounted on Samsung S Plus I9001), this is suitable for Android kernel
ARM Cortex-A8. L1 Data cache = 32 KB. 4-Way, 64 B/line. Instruction TLB size = 32 items. In-order, dual-issue, superscalar microprocessor core. 13-stage main integer pipeline. 10-stage NEON media pipeline for executing NEON and VFP instruction sets.
ARM brings some perspective to performance improvement in their presentation “ARMv8: Advantages for Android” where they compare performance improvements of Aarch64 (64-bit ARM instructions) over Aarch32 (32-bit ARM instructions) running benchmarks compiled with either instructions set I was wondering how does a modern ARM chip based on ARM Cortex A8 compare, in clock-for-clock performance and capability, to a modern x86 chip such as a Core 2 Duo or Core i5? I realise due to the different instruction sets it’ll depend heavily on what you’re doing.
