Coherency

Cache coherency Cache incoherence due to DMA DMA can lead to cache coherency problems.

The Old and New Testaments were composed over many centuries, so the miracle of scripture’s coherency and unity is ultimately due to the divine authorship of the biblical canon.

Access to RAM is serialized; this and cache coherency issues causes performance to lag slightly behind the number of additional processors in the system.

All the parts of that book did not add up; all the ingredients did not make a coherency.

An example would be a control system reading both the normally open (NO) and normally closed (NC) poles of a SPDT selector switch against common, and checking them for coherency before reacting to the input.

Coherency requirements are not as strict as those for military systems because individual signals ordinarily do not need to be separated.

Contrary to strict buffering, a caching process must adhere to a (potentially distributed) cache coherency protocol in order to maintain consistency between the cache's intermediate storage and the location where the data resides.

Inserted memory instructions were used to maintain cache coherency.

Second, rasterization can improve cache coherency and reduce redundant work by taking advantage of the fact that the pixels occupied by a single primitive tend to be contiguous in the image.

Targets supporting cache coherency are also required to terminate bursts before they cross cache lines.

The coherency matrix contains all second order statistical information about the polarization.

This matrix can be decomposed into the sum of two idempotent matrices, corresponding to the eigenvectors of the coherency matrix, each representing a polarization state that is orthogonal to the other.

Write-through operation is common when operating over unreliable networks (like an Ethernet LAN), because of the enormous complexity of the coherency protocol required between multiple write-back caches when communication is unreliable.
