Abstract
Method of informing a processor that a coprocessor instruction is not executable by a coprocessor is described. The coprocessor, instantiated in configurable logic, is configured to execute a subset of coprocessor instructions, excluding user-selected instructions not instantiated. The processor is coupled to the coprocessor via a controller. The coprocessor instruction is sent from the processor to the controller, which queries control logic to determine whether the coprocessor is configured to execute the coprocessor instruction. If a control bit is set to disable an instruction or group of instructions, the coprocessor instruction is not executable by the coprocessor.
