Abstract
A coprocessor performs an overhead function of a Java virtual machine executing in a main processor. The coprocessor includes memory access circuitry configured to access a memory also accessible by the host processor. Pointer receiving circuitry is configured to receive at least one pointer to data in the memory pertinent to the overhead function. Function performing circuitry is configured to perform the overhead function to operate on the data in the memory pointed to by the at least one pointer. Result passing circuitry configured to pass a result back to the main processor. For example, overhead functions that may be performed by the coprocessor include bytecode verification, just-in-time compiling and garbage collection.
