摘要

PROBLEM TO BE SOLVED: To provide an apparatus for accessing data from a portion of a level-two memory or data from a level-one memory.SOLUTION: An apparatus 100 includes a level-one cache 104 and a level-two memory 112. A first portion 108 of the level-two memory is coupled to an input port and is addressable in parallel with the level-one cache. The apparatus comprises control means configured to: determine a value of a status bit associated with the input port in response to receiving a specific memory access request; and route the specific memory access request to the first portion of the level-two memory via the input port.SELECTED DRAWING: Figure 1
