System-Level Design sat down to discuss coherency with Mirit Fromovich, principal solutions engineer at Cadence; Drew Wingard, CTO of Sonics; Mike Gianfagna, vice president of marketing at Atrenta, ...

As complexity increases and the industry increasingly shifts away from ASICs to SoCs, the concept of coherency is beginning to look more like a stack of issues than a discrete piece of the design.

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 ...

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 ...
