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 ...

The US Court of Appeals for the Federal Circuit, addressing the issue of whether certain factual and legal conclusions relating to obviousness were supported by substantial evidence, held that the ...

Until recently, coherency was something normally associated with DRAM. But as chip designs become increasingly heterogeneous, incorporating more and different types of compute elements, it becomes ...

Managing a cache so that data are not lost or overwritten. For example, when data are updated in a cache but not yet transferred to the target memory or disk, the chance of corruption is greater.

Complex chips need coherent and non-coherent sub-NoCs to ensure efficient data paths. Correct hierarchy is essential.

Complete CCIX IP solution supports cache coherency, allowing faster and more efficient sharing of memory between processors and accelerators Reliability, availability and serviceability (RAS) features ...

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.

If multiple devices, such as the CPU and peripherals, access the same cacheable memory region, cache and memory can become incoherent. This is illustrated in Figure 7. Suppose the CPU accesses a ...
