Chip maker ARM has introduced a pair of multi-core chips, viz. the Cortex-R5 and Cortex-R7, for use in 3G and 4G mobile devices.

The Cambridge-based manufacturer said that the Cortex-R5 and Cortex-R7 processors were produced after mingling firm's more than twenty years of proficiency in low-power design with the latest high-performance & real-time technologies.

Both of the Cortex-R5 and Cortex-R7 can be implemented as single or dual cores processors, at clock speeds of up to 1.66MHz or 2.53MHz respectively. One core can be set to handle download traffic and the other upload traffic.

Smartphone suppliers can choose to lower the clock speed in order to make a device consume less power and run more.

The Cortex-R7 will be used in LTE-Advanced compatible devices. It features faster hardware support for arithmetic operations.

The manufacturer claims that its new processors promise higher performance, reliability, efficiency and greater error management.

Richard York, the director of product marketing at ARM, said that the firm would announce more products at the upcoming Mobile World Congress.
