ARM Cortex-A processor may get all the media buzz as they are found in popular consumer devices such as smartphones, but ARM also provides Cortex-R processors with real-time capabilities that are found in cars, hard drives, and other embedded systems requiring high reliability, fault tolerance, and deterministic real-time responses. The company has just announced Cortex-R8 real-time core that should double the performance of Cortex-R7 core, and targeting mainly storage devices such as SSDs and HDDs, as well as next generation LTE and 5G modems. Cortex-R8 key features: Microarchitecture – 11-stage pipeline with instruction pre-fetch, branch prediction, superscalar and out of order execution, register renaming, parallel execution paths for load-store, MAC, shift-ALU, divide and floating-point. Also features a hardware divider and is software compatible with the ARM9, ARM11, Cortex-R4, Cortex-R5 and Cortex-R7 embedded processors. Instruction Set – ARMv7-R architecture with Thumb-2 and Thumb. Support for DSP extensions, as well as an […]
