Adaptive prefetch for irregular access patterns |
摘要 |
A computer program product determines whether a loop has a high usage count. If the computer program product determines the loop has a high usage count, the computer program product determines whether the loop has an irregularly accessed load. If the loop has an irregularly accessed load, the computer program product inserts pattern recognition code to calculate whether successive iterations of the irregular memory load in the loop have a predictable access pattern. The computer program product implants conditional adaptive prefetch code including a prefetch instruction into the output code.
