Abstract
A computer system is disclosed. The computer system includes a higher level cache, a lower level cache, a decoder to decode instructions, and a circuit coupled to the decoder. In one embodiment, the circuit, in response to a single decoded instruction, retrieves data from external memory and bypasses the lower level cache upon a higher level cache miss. In another embodiment, the circuit, in response to a first decoded instruction, issues a request to retrieve data at an address from external memory to place said data only in the lower level cache, detects a second cacheable decoded instruction to said address, and places said data in the higher level cache.
