Key Facts:
• ARM’s Cortex-R5 processor extends the feature set of the Cortex-R4 processor to enable higher levels of system performance, increased efficiency and reliability, and enhanced error management in dependable real-time systems. These system-level features include a high priority Low-Latency Peripheral Port (LLPP) for fast peripheral reads and writes, and an Accelerator Coherency Port (ACP) providing cache coherency for increased data transfer efficiency and more reliable firmware.
• The Cortex-R7 processor greatly extends the performance levels of the Cortex-R series beyond any existing capabilities through 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.
• The real-time features of the two new Cortex-R series processors are particularly suited to advanced mobile baseband applications, such as LTE and LTE-Advanced, and includes support for high frequency interrupts along with fast and deterministic control of data transmission between cellular base-stations and mobile devices.
• For HDD and SSD mass storage systems the Cortex-R series processors provide the optimum balance between processor performance, reliability and real-time response, along with ease of development and advanced CoreSight™ debug to support current and future system chip architectures that address this fast-moving market.
• For embedded applications requiring high performance combined with high reliability, the new processors provide a suite of safety-critical features, including both soft and hard error management, redundant dual-core systems using two processors in lock-step, and error correcting codes (ECC) on all external buses.
• 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.
