摘要:
A cache memory which loads two memory values into two cache lines by receiving separate portions of a first requested memory value from a first data bus over a first time span of successive clock cycles and receiving separate portions of a second requested memory value from a second data bus over a second time span of successive clock cycles which overlaps with the first time span. In the illustrative embodiment a first input line is used for loading both a first byte array of the first cache line and a first byte array of the second cache line, a second input line is used for loading both a second byte array of the first cache line and a second byte array of the second cache line, and the transmission of the separate portions of the first and second memory values is interleaved between the first and second data busses.
