The apparatus includes combinatorial logic associated with each instruction byte of the stream, each configured to receive the associated instruction byte and the next instruction byte of the stream and to generate in response thereto a first length, a second length, and a select control. A multiplexor associated with each of the combinatorial logic selects and outputs one of the following inputs based on the select control received from the combinatorial logic: a zero input and the second length received from the combinatorial logic associated with each of the next three instruction bytes of the stream. An adder associated with each of the combinatorial logic and multiplexor adds the first length and the output of the multiplexor to generate the length of the instruction."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Apparatus for efficiently determining instruction length instruction within a stream of x86 instruction bytes","description":"An apparatus efficiently determines the length of an instruction within a stream of instruction bytes processed by a microprocessor having a variable instruction length instruction set architecture.
