Abstract
Garbage collection or other computational work accesses memory which is located outside processor registers. Some embodiments specify at least some of the memory accesses and separate them from other computations, and utilize a memory access state machine to control the execution of both kinds of computation. Code that employs memory access results is placed in a run routine which is divided between respective states of the state machine. The specified memory accesses are invoked from a state code, and overlap other computation. A prefetch buffer may be dynamically sized based on the availability of space in the prefetch buffer. Code for shared work, such as address relocation code, may be placed in its own state structure. Candidate code for possible separation into a specified memory access routine may be automatically recognized.
