Open source flavour to CSR, ARM Cortex-A5 licence deal

ARM has signed a license agreement with wireless chip firm CSR covering the Cortex-A5 MPCore and Cortex-A9 MPCore multicore processors, writes Richard Wilson.

CSR will use the multicore processors in a new range of chips for in-vehicle navigation and portable navigation devices.

“We are now positioned to fully respond to market needs by exploiting the total potential of ARM powered system-on-chip solutions for next generation consumer devices and automotive systems,” said Kanwar Chadha, chief marketing officer, CSR.

CSR acquired its main GPS radio technology two years ago with the acquisition of US-based GPS chipset firm SiRF.

The deal demonstrates the growing importance of GPS technology in smartphones and handheld terminals.

It also endorses the dominance of ARM’s low power processor technology in mobiles.

“This latest agreement demonstrates the continued market momentum for the ARM Cortex-A series processors and ARM MPCore technology,” said Eric Schorn, v-p marketing, processor division, ARM.

There is also a strong open-source flavour to the license deal as the Cortex-A5 processor software ecosystem includes Android, Linux and Ubunto as well as the Microsoft Windows Embedded and Symbian OS.

The Cortex-A5 and Cortex-A9 processors can contain up to four independently configured but fully coherent cores, carrying out multiple tasks on each one in parallel.
