The QED RM7000 Processor

The RM7000 is a higher performance successor of the R5000 with built-in 256 KB L2 cache and a controller for optional L3 cache. It was primarily targeted at high end embedded designs such as internetworking, high-performance image manipulation and high complexity printing. Despite of being targeted at the embedded market SGI did use the RM7000 to upgrade it's O2 workstation to the O2+.
