cache controller

The hard disk is also fast, without the benefit of a cache controller.

Austek however was unable to compete with Intel in the cache controller market.

There is an L3 cache controller, but the actual memory is off-chip.

The backup cache controller was located on the VC chip.

In early designs a cache miss would force the cache controller to stall the processor and wait.

Austek produced a number of digital signal processing chips, but their most successful products were cache controllers.

Integrated low-latency level-2 cache controller, up to 4 MB per cluster.

Instead, the processor has an on-chip cache controller which controls separate external data and instruction caches.

All cache controllers monitor the bus.

Each cache line also has a valid bit and a dirty bit, stored in the cache controller.

The cache controller is on-die.

The Intel 82497 is a Cache Controller for the Pentium processor.

The MMU die contains the memory management unit, cache controller and the external interfaces.

To prevent this, every cache controller monitors the bus, listening for broadcasts which may cause it to invalidate its cache line.

The B-cache is controlled by on-die external interface logic, unlike the 21064, which required an external cache controller.

The part, due to start appearing in products next year, will be clocked at 60MHz and will include on-chip cache controller and new graphics instructions.

In speed terms the RapidCad is pretty close to the theoretical speed of a 486 without burst I/O and cache controller.

Improvements were the addition of an on-chip secondary cache controller that supported up to 2 MB of cache.

DC592 cache controller (codenamed COW or "C-chip" during development)

When writing a block in state "valid" its state is changed to "dirty" and a broadcast is sent out to all cache controllers to invalidate their copies.

The 82497 Cache Controller implements the MESI write-back protocol for full multiprocessing support.

It uses high-speed, state-of-the-art packet switching techniques incorporated into the cache controller for symmetrically connecting over 64 Viking CPUs.

The leftover tag bit is instead used to store the cache line dirty bit, and all 16 Kbits in the cache controller are used for valid bits.

Typically, ccNUMA uses inter-processor communication between cache controllers to keep a consistent memory image when more than one cache stores the same memory location.

When a write operation is observed to a location that a cache has a copy of, the cache controller invalidates its own copy of the snooped memory location.
