British chip design giant ARM has announced its latest chips for the smartphone market, the Cortex-R5 MPCore and Cortex-R7 MPCore, adding in support for LTE and LTE-Advanced platforms.
Further shoring up its defences against Intel's assault on the smartphone market with its promised low-power Atom variants, ARM's newest Cortex-R chips offer binary compatibility with the company's existing processors while adding in new features and technologies that the company hopes will keep in on top.
Designed for both smartphone and embedded use, the Cortex-R5 and Cortex-R7 chips are available in single- or dual-core designs, although ARM recommends that the Cortex-R7 - which includes improved symmetric multiprocessing features over its cheaper brother - is used for dual-core implementations.
Both chips include improvements on ARM's Cortex-R4 design, adding in a high-priority low-latency peripheral port and an accelerator coherency port for cache sharing to improve performance, efficiency, and reliability.
The Cortex-R7, ARM's flagship Cortex R-series chip, includes features designed to make it suitable for high-performance LTE-Advanced smartphones over the coming years, including out-of-order execution for vastly improved performance, dynamic register renaming, improved branch prediction logic, and superscalar execution.
The company has also confirmed that the Cortex-R7 design is ready for production on a 28nm process for smaller, lower-power chip implementations, although has yet to announce if any hardware partners are planning on bringing such a version to market in the near future.
Speaking of the launch, ARM vice president Eric Schorn stated: "The simultaneous launch of the Cortex-R5 MPCore and Cortex-R7 MPCore processors clearly delineates our leadership position as the architecture of choice for current and future mobile baseband and advanced storage applications, as well as building on our unparalleled position in the wider embedded market.
"These two advanced processors bring together more than 20 years of ARM expertise in low-power design with a host of new high-performance and real-time technologies which enables our Partners to future-proof their designs based on a single consistent architecture."
The chip designs are available for licensing to fabricators immediately, and ARM has already confirmed four big-name licensees in the mass storage, vehicular, and mobile markets as having purchased rights for the new processors.
