The ARM® AMBA® 4 Coherency Extension (ACE™) specification was officially published more than a year ago. The main driver for the ACE spec is the need to support hardware-managed cache coherency, ...

Scaling processing performance beyond the frequency and power envelope of single core systems has led to the emergence of multi-core clusters. Data access management within such processing systems ...

A processor cache is an area of high-speed memory that stores information near the processor. This helps make the processing of common instructions efficient and therefore speeds up computation time.

Since the earliest days of microprocessors, system designers have been plagued by a problem in which the speed of the CPU's operation exceeded the bandwidth of the memory subsystem to which it was ...

While traditional single core systems employ a dedicated cache, theintroduction of multi-core platforms presents the opportunity toconsider the shared use of cache by multiple processors. Designs ...
