Abstract: A portable platform device is described comprising a central body and a plurality of legs located on the central body near a distal end of the central body and spaced radially around the central body wherein the legs are configured for placement on a surface. A ball joint is mounted at its distil end to a proximal end of the central body and a platform is configured to be fixed to a proximal end of the ball joint and configured to be adjustable to a horizontally level and vertically plumb position.

Abstract: A caching circuit includes tag memories for storing tagged addresses of a first cache. On-chip data memories are arranged in the same die as the tag memories, and the on-chip data memories form a first sub-hierarchy of the first cache. Off-chip data memories are arranged in a different die as the tag memories, and the off-chip data memories form a second sub-hierarchy of the first cache. Sources (such as processors) are arranged to use the tag memories to service first cache requests using the first and second sub-hierarchies of the first cache.

Abstract: A data latching mechanism uses Column Address Strobe (CAS) signals to effect one-cycle DRAM page-mode access at high operation frequency.
