<p>The crowned champion of the ring test, the PRU hits 16.6MHz</p>
-<p>This ring oscillator runs on the beagleboard's PRU -> 'Programmable Realtime Unit'. The PRU is especially insteresting for the ring test because it (a 200MHz cpu) shares memory with the Beagleboards' larger onboard processor. This is probably exciting when we run big (and asychronous) software on the large processor, (i.e. an OS, which processes operations in a queue) and want to do tightly controlled realtime work at the same time. Memory sharing means we can pass messages between these contexts quickly.</p>
+<p>This ring oscillator runs on the PocketBeagle's PRU -> 'Programmable Realtime Unit'. The PRU is juse one component of the SOC which makes up a pocket beagle, namely the <a href="https://octavosystems.com/octavo_products/osd335x-sm/">Octavo Systems' OSD3358</a> with 256 BGA pads. The same PRU is embedded in the <a href="http://www.ti.com/product/AM3356/samplebuy">TI Sitara AM3356</a> processor.</p>
