Abstract
A novel method to quickly decode a block-code in a load buffer and compare it against multiple wake-up signals in an out-of-order processor. A block-code is used to describe the blocking condition that prevents a load operation from being dispatched. Each wake-up signal indicates that the blocking conditions corresponding to certain block codes have been resolved. For each entry in the load buffer, a dynamic decoder decodes the block-code and a compare logic determines if the wake-up signal corresponding to the block-code is active. If the wake-up signal corresponding to the block-code is active, the load entry is marked ready for dispatch. Since, the blocking conditions may change each clock cycle, the decode and compare should be done each clock cycle to achieve optimal performance. Faster decode and compare may permit higher clock frequencies if the processor is limited by the decode and compare.
