xCORE Audio

"By exchanging multiple silicon pieces for a single XMOS chip, we have lowered costs and harnessed the flexibility to integrate specific, differentiating functionality in the Control 15 that other chips simply didn’t allow. Developing on xCORE multicore microcontrollers showed us the next generation of programmable silicon"

XMOS's Hi-Res processors offer high-resolution audio interfacing capabilities to deliver precise output with low noise/distortion for soothing, high-quality sound at a price-point that is affordable for mass-market consumer audio applications. xCORE-AUDIO Hi-Res processors support the full range of Hi-Resolution file formats, including PCM audio encoded at 384kHz/32-bit and DSD 2.8 MHz/5.6 MHz audio using any PC or MAC. The built-in USB interface supports a wide array of digital devices, including the iPod, iPhone and iPad devices; and PC or Mac. GPIO are available for implementing Human Machine Interfaces (HMI) and/or the control of external audio ADC/DAC devices. xCORE-AUDIO Hi-Res is available in easy-to-use 64-pin TQFP packaging for low-cost system integration.
