Abstract
A system provides a method and apparatus for accessing information in a cache in a data processing system. The system optimizes a speed-critical path within the cache system by using a prediction scheme. The prediction scheme subdivides the address range of address bits and compares the portions separately. A comparison of a critical portion of the address, along with a prediction bit, are used to generate a prediction.
