Beken Chooses BA22 Processor to Satisfy Tight Constraints in New Mobile Bluetooth Audio Chip

San Francisco, CA — Design Automation Conference, June 02, 2014 -- Beken Corporation in China faced a significant challenge designing its upcoming high-performance Bluetooth audio chip with all the latest innovations but within the mobile device requirements of its OEM customers. Competitive analysis and careful market review led them to choose the BA22-RT 32-bit Real-Time Embedded Processor IP core available from semiconductor intellectual property provider CAST, Inc.

To enable customers to produce feature-rich Bluetooth audio products with outstanding low-power and low-cost advantages, Beken needed to design a very computation- and memory-efficient system capable of supporting real-time audio decoding plus a Bluetooth stack with the A2DP (Advanced Audio Distribution Profile), AVRCP (Audio/Video Remote Control Profile), and HFP (Hands free Profile) protocols.

The choice of 32-bit embedded processor to handle the Bluetooth algorithms and run application code was most critical to the project’s success, and Beken sought to differentiate their offering by looking beyond the most obvious suppliers. They found a key factor to be the size of the programming code each processor required, since smaller code means smaller physical memory is needed, and physical memory size is one of the major determinants of system-wide power consumption and also a critical contributor to the cost of Bluetooth subsystems.

Beken’s evaluation determined that their program code for the BA22-RT core fits in a 128KB memory, versus 170KB for the next-closest competitor. This means Beken can use a 128KB memory unit rather than a more expensive 256KB unit, cutting costs in a market where every penny per chip matters.

With the BA22-RT core’s performance and other characteristics matching or exceeding other CPUs, Beken decided to license the core from CAST, along with a complement of pre-integrated peripherals that saved them development time. Design and testing is nearing completion, and the new Beken Bluetooth chip is expected to hit the market later this year.
