LONDON – Wireless and audio chip vendor CSR plc has signed a deal with ARM Holdings plc under which it has licensed both the Cortex-A5 and the high-end Cortex-A9 cores in multiprocessing form. CSR says it wants to use the cores in automotive navigation and location-aware consumer equipment, especially in Brazil, Russia, India and China.
CSR (Cambridge, England) is best known as a vendor of Bluetooth chips but its technology portfolio includes Bluetooth, GPS, FM, Wi-Fi (IEEE802.11), UWB, NFC and the company is already an ARM licensee.
The Cortex-A5 and Cortex-A9 processors can contain up to four independently configured coherent cores, carrying out multiple tasks. However, that complexity is hidden from the programmer and the processors can be programmed like a single-core processor by utilizing one of the many SMP-aware operating systems.
The Cortex-A series processors feature power management features including adaptive gating, dynamic voltage and frequency scaling and the ability for each core to go independently into standby, dormant or power-off energy management state. The A5 and A9 are mutually compatible so applications can run on either and have access to third-party products and services including Android, Adobe Flash, Java, Linux, Microsoft Windows Embedded and Symbian.
"This licensing agreement expands our existing ARM processor portfolio, and is a clear demonstration of our commitment to enhance consumer experience with our platforms by investing in leading edge IP," said Kanwar Chadha, chief marketing officer of CSR, in a statement.
"Combining our state of the art location and connectivity expertise with two software-compatible processors, based on the standard ARM architecture will enable us to reduce our development costs while delivering leading edge products to market in a timely manner," added Babak Bastani, vice president of global chip design for CSR, in the same statement.
