ARM introduced its new Cortex-R5 MPCore and the Cortex-R7 MPCore processors for use in 3G and 4G mobile baseband, mass storage, automotive and industrial markets. 
For mobile baseband, the real-time features of the two new Cortex-R series processors are particularly suited to LTE and LTE-Advanced. ARM includes support for high frequency interrupts along with fast and deterministic control of data transmission between cellular base-stations and mobile devices.
Both the Cortex-R5 MPCore and Cortex-R7 MPCore processors can be implemented as either single or dual cores.
However, the Cortex-R7 MPCore processor features proven SMP multicore technology, including new real-time enhancements, enabling performance scalability and energy efficiency to be optimized for the intended application. These processors continue to demonstrate the effectiveness of the ARM architecture by delivering the most effective power-efficient solutions for mobile and portable products.
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.http://www.arm.com http://www.arm.com/products/processors/cortex-r
