Abstract
One aspect of the invention relates to a method for processing load instructions in a superscalar processor having a data cache and a register file. In one embodiment, the method includes the steps of dispatching a misaligned load instruction to access a block of data that is misaligned in the cache; while continuing to dispatch aligned instructions: generating a first access and a final access to the cache in response to the misaligned load instruction; storing data retrieved from the first access until data from the final access is available; reassembling the data from the first and final access into the order required by the load instruction; and storing the re-assembled data to the register file.
