What is Pipeline Burst Cache? definition and meaning

Pipeline Burst Cache is a secondary cache also known as an L2 cache that allows data to be transferred much faster by distributing the data pulled from memory over three full clock cycles. It is an essential part of microprocessors that use a superscalar architecture, but it requires a specific, corresponding, and synchronous type of RAM called SDRAM to function.

Geek Expert explains the pipeline burst cache

This type of RAM is one whose chips can be synchronized with the clock of the microprocessor and therefore can easily measure and track its clock cycles. By spanning three of these cycles, there is initially a minor delay, but once this is done the requests can be queued by the cache and all subsequent retrieve requests take just one cycle, which means things generally run a lot. faster than they would without the L2 cache.

Pipeline burst caches also support burst transfers: By leveraging SDRAM chips, the pipeline can also serve a group or row of cache content at a time when the processor requests the first item in that row. Or this group. This means that everything else is essentially pre-loaded and available much faster than if each item had to be ordered manually and specifically. This is because the introduction and use of pipeline burst caches reduces CPU timeouts and increases cache operations.

The L2 cache generally works in one of two modes: the burst mode mentioned above and the standard pipeline mode. Information can only be obtained in pre-bursts, whereas in pipeline mode, the cache makes its content available to both cache and RAM.
