Definitions for "Backside Bus"
A dedicated channel between the CPU and a Level 2 cache. The so-called dual independent bus (DIB) architecture allows a processor to use both this and the frontside bus (which connects the CPU with main memory) simultaneously. See also Frontside Bus.
There are two types of buses that carry data to and from a computer's CPU. T...
A special bus designed to attach the microprocessor directly to the cache memory in a Dual Independent Bus (DIB) architecture system.  The frontside bus connects the microprocessor to the main system memory.  Used in Intel Pentium II and later systems for increased performance.  Prior to the DIB architecture, the system bus was used for both purposes.
