Back Side Bus (BSB)
BSB refers to the bus that connects
the CPU to the L2 cache. The speed of
BSB is totally dependent on the speed of the CPU.
The L2 cache stores
the instruction and data that need to be processed. Whenever these data and
instructions are needed by the processor ,the information is transferred using
BSB. Since BSB transfers data directly to the CPU, it is very fast as compared
to Front Side Bus(FSB). BSB describes the interface between the L1 cache on the processor with
the L2 cache.
