LONDON ARC International has started sampling an MP3 decoder core for its Sound Subsystem that operates at under 7 MHz and dissipates less than 0.46 mW of power.
The device, made in TSMC's 90 G process, is targeted at MP3 playback and dissipates the low 0.46 mW when decoding a typical MP3 stream at 128kbits/second and per 44.1kHz.
ARC (St Albans, England) says this is a 20 percent improvement in power consumption compared with its nearest, but un-named, competitor in this sector.
The company adds that at 0.83mm sq with the TSMC process, including RAMs, the ARC Sound Subsystem is already one of the industry's smallest such parts for handheld audio applications.
The IP was developed at Alarity, the Rutherford, New Jersey based multimedia IP design group ARC bought earlier this year.
"Developing an MP3 decoder or any other multimedia codec for ARC CPU cores and subsystems is greatly enhanced by inherent configurability," said Felix Litvinsky, vice president of business development at ARC and former CEO of Alarity, in a statement.
With a configurable processor architecture, programmers can now profile code to identify execution bottlenecks and add an instruction that vastly accelerates code performance, freeing them to create optimized software on optimized hardware, adds Litvinsky.
