Cortex R-series cores target real-time apps

The Cortex-R5 MPCore and the Cortex-R7 MPCore processor IP target real-time embedded applications such as 3G and 4G mobile baseband, mass-storage, automotive, and industrial markets. The cores feature low-latency, deterministic responsiveness, and hard- and soft-error management for dependable systems.

The R5 yields 1.66 DMIPS/MHz at up to 480 MHz using an eight-stage pipeline, while the R7 delivers 2.53 DMIPS/MHz at up to 600 MHz with an 11-stage pipeline. Both yield ~11 DMIPS/mW. They can be implemented as either single or dual cores, and the R7 MPCore features symmetric multiprocessing technology. Dual-core configurations can be lock-step for safety or split for 2x performance. (Cortex IP is licensed to processor manufacturers — R5, available now; R7, 3rd qtr.)
