I would normally not mention a Bluetooth audio chip in this blog, but you may remember my posts about Beyond Semi BA21 and BA25 RISC cores. The Slovene company’s IP cores are not found in many silicons right now, but one Chinese fabless semiconductor company called Beken Corporation, has chosen BA22-RT core instead of an ARM core for their latest Bluetooth audio chip.
Beken required a 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, and it also had to provide both a low cost and low power consumption solution.
During their evaluation of several 32-bit IP cores, Beken engineers noticed their program code would fit into a 128KB memory using BA22-RT (Real Time) core, instead of 170 KB for a competing solution simply referred to as “the most obvious supplier”, which is likely to be ARM. So they decided to go ahead with BA22-RT with 128 KB memory, instead of another solution with 256 KB memory, in order to save on cost, decrease overall power consumption, and because BA22-RT core matched their other requirements.
Design and testing is almost completed, and Beken Bluetooth chip is expected to hit the market later this year.
