LONDON – Processor IP licensor ARMHoldings plc has announced the addition of cache coherency to the AMBA 4 interfaceand protocol specification that supports communications between cores. The AMBA 4 ...
Part 1: A look at the impact of communication across multiple processors on an SoC and how to to make that more efficient. Managing how the processors in an SoC talk to one another is no small feat, ...
More processors on SoCs means more sophisticated cache control. This article describes formal techniques for verifying cache coherency for the ARM AMBA AXI Coherency Extensions (ACE) protocol. Fig 1.
