Intel Bay Trail / Cherry Trail¶
Intel Bay Trail platform is based on an Atom CPU and a Tensilica HiFi2 EP DSP. It relies on both internal memory and caches to access DDR memory. The Bay Trail processor relies on a 25 MHz oscillator.
Supported commercially-available platforms include the MinnowBoard Turbot, tablets and laptops built for Windows (SOF requires a Linux installation).
The Cherry Trail platform is similar to Bay Trail but it relies on a 19.2 MHz osciilator. Supported commercially-available platforms include the Up board and devices built for Windows (SOF requires a Linux installation).
Bay Trail and Cherry Trail Chromebooks can support SOF but the official images are still based on the closed-source firmware solution.
