  • System and method for parsing and executing a single instruction stream using a plurality of tightly coupled parsing and execution units
    Patent number: 5822570
    Abstract: A system and method for dividing execution of an instruction stream among a plurality of tightly coupled instruction execution units is presented. The present invention couples a plurality of instruction execution units tightly and provides a mechanism whereby control may be passed from one instruction execution unit to another instruction execution unit without raising exceptions or terminating normal execution of the instruction stream. The present invention employs a caller instruction execution unit that has a complete parser and the capability to emulate at least a portion of the instruction stream and at least one partial instruction execution unit. The caller instruction execution unit passes control to the partial instruction execution unit and allows the partial instruction execution unit to execute as many instruction of the instruction stream as it can.
