XMOS is shipping its xCORE-AUDIO processor family and sampling its Gigabit Ethernet enabled xCORE-200 multicore microcontroller family.
“There’s a big trend for much better audio content,” XMOS CEO Nigel Toon told EW, “there’s a backlash against MP3. They’re going to much higher quality helped by the fact that you can now transfer big audio files. Sony is pushing hi-res audio DSD digital streaming. The move is from CD quality at 44KHz with 16bits resolution to 384KHz with 24bits resolution.”
The xCORE-AUDIO processor is built on XMOS’ xCORE-200 multicore microcontroller processor technology, with stereo Hi-Res-2. There are two product lines: xCORE-AUDIO Hi-Res, targeting stereo hi-res USB headphone amplifiers, DACs and AVR systems, and xCORE-AUDIO Live for prosumer and professional audio applications including DJ kits, mixing and audio content creation.
“The demand for high-resolution audio content for consumption on the move, and the complexities of creating the same content in the studio and concert hall, are well served by our USB 2.0 and networked audio solutions,” said Toon, “by selecting output formats from our audio I/O libraries, and using multicore power to implement complex DSP functions, XMOS delivers professional audio solutions at consumer prices.” The chips will cost $2 in volume quantities.
xCORE-AUDIO Hi-Res 2 supports: USB 2.0 (Full-speed and High-speed); USB Audio Class 1.0; USB Audio Class 2.0, USB Firmware Upgrade (DFU) 1.1.; I2S, DSD and SPDIF output formats; 44.1kHz, 48kHz, 88.2kHz, 96kHz, 176.4kHz, 192kHz, 352.8kHz, 384kHz. The xCORE-AUDIO Hi-Res 2 development board is also now available.
