The purpose of the MDCs is to act as a buffer between the 512-bit memory bus and the 128-bit LSB bus.
32.
We introduce new cooperative theory ( Mashy ), confirming that the memory bus [ 20 ] and the Ethernet are generally incompatible.
33.
Dual ported buffers and registers allow the 82497 to concurrently handle CPU bus, memory bus, and internal cache operation for maximum performance.
34.
However, by continuing with a bandwidth-constraining 64-bit memory bus, S3 guaranteed this graphics card would never be a performance part under 32-bit color.
35.
It was the first chip to use clock doubling, whereby the processor performs two clock cycles per single cycle of the memory bus.
36.
The memory bus usually is handled by a single memory controller, located in the north bridge which is a part in the cpu today.
37.
Because the custom chipset shares RAM ( and therefore the memory bus ) with the CPU, throughput increases measurably if the display is disabled.
38.
The memory bus speed of a typical modern machine runs at 100 megahertz, even as processors are now beginning to cross the one-gigahertz line.
39.
The shared memory model used to coordinate work between the various CPUs caused memory bus contention and was known to be a source of inefficiency.
40.
The caches and memory modules all communicated with each other over a 2 x 64 bit bus called the DMB ( Dataflow Memory Bus ).
