摘要:
A method comprising loading a plurality of data bytes from a data cache (304) in response to a load instruction, determining the most significant bit of at least one of the data bytes using a first logic, arranging at least some of the data bytes onto a data bus (318) using a second logic substantially coupled in parallel with the first logic, and performing a sign extension on the data bus using the second logic.
