Patent
CA 2277638
Apparatus, methods, and computer program products are disclosed that improve the operation of a computer that uses a top-of-stack cache by reducing the number of overflow and underflow traps generated during the execution of a program. The invention maintains a predictor value that controls the number of stack elements that are spilled from, or filled to, the top-of-stack cache in response to an overflow trap or an underflow trap (respectively). The predictor reflects the history of overflow traps and underflow traps.
