摘要：A processor includes a decoder that decodes an instruction that instructs the processor to perform subsequent computations in an approximate manner and a functional unit that performs the subsequent computations in the approximate manner in response to the instruction. An instruction instructs the processor to clear an error amount associated with a value stored in a general purpose register of the processor. The error amount indicates an amount of error associated with a result of a computation performed by the processor in an approximate manner. The processor also clears the error amount in response to the instruction. Another instruction specifies a computation to be performed and includes a prefix that indicates the processor is to perform the computation in an approximate manner. The functional unit performs the computation specified by the instruction in the approximate manner specified by the prefix.
