ARM reveals Cortex-R8 real-time processor

ARM has announced a new real-time processor, called Cortex-R8 that is designed to double the performance of ARM modem and mass storage device processors. The new chip is based on the ARMv7-R architecture and can be used in single-to-quad-core configurations at clock speeds that reach 1.5 GHz.

The new Cortex-R8 processor is made on 28 nm HPM process and has enough performance to be used in LTE-A Pro and 1st generation 5G modems. The chip features an architecture with 11-stage, superscalar, out-of-order pipelines with advanced dynamic and static branch prediction, dynamic register renaming and non-blocking load-store units. In addition to this the Cortex-R8 SoC has enhanced error detection and correction capabilities to ensure data integrity, an integrated generic interrupt controller (GIC), a Snoop Control Unit (SCU) and timers to reduce latency and enable symmetric multiprocessing in a dual-core configuration. Moreover the processor provides a flexible local memory system that supports large Tightly Coupled Memory (TCM), local shared memory, a shared coherent peripheral port, and a per core fast path port enabling SoC designers to reach the most demanding real-time requirements within constrained silicon resources.

The new ARM Cortex-R8 chip will soon find its way into new devices.
