dual interface bus (DIB)

The Dual Interface Bus(DIB) is a two-bus architecture of microprocessors for accelerating the data rate. This bus architecture is intended to prevent bottlenecks in performance-intensive graphics applications.

The two bus systems, which work separately and independently of each other, are used to connect to the cache and the main memory.

The DIB architecture is used in some Pentiums. The Pentium II has such a dual-bus architecture, with one of the buses acting as the L2 cache bus and the other as the system bus between the processor and RAM. Since both buses are completely independent of each other, the Pentium II can work with both buses simultaneously, which results in a doubling of the data rate.
