ARM today announced the launch of the ARM Cortex-R5 MPCore and the Cortex-R7 MPCore processors for use in 3G and 4G mobile baseband, mass storage, automotive and industrial markets. Both cores complement its R4, which was launched in 2006.
The R5, which features an eight stage pipelined core, runs at 1.66DMIPS/MHz. Single and dual core options are available. The R5 is an asymmetric design while the R7 can be designed as a symmetric multiprocessor.
The R7 enables “much greater performance," according to ARM with an 11 stage pipeline, and is also available in single or dual core formats, with each core offering 2.53DMIPS/MHz. The Cortex-R7 processor extends the performance levels of the Cortex-R series via the introduction of new technology, including out-of-order execution, dynamic register renaming combined with improved branch prediction, superscalar execution and faster hardware support for divide, floating point and other functions.
Both processors are available for licensing today and four tier one licensees in the mass storage, automotive and mobile baseband markets already have designs underway according to ARM.
