摘要： A register renaming system for out-of-order execution of a set of reduced instruction set computer instructions having addressable source and destination register fields, adapted for use in a computer having an instruction execution unit with a register file accessed by read address ports and for storing instruction operands. A data dependance check circuit is included for determining data dependencies between the instructions. A tag assignment circuit generates one or more tags to specify the location of operands, based on the data dependencies determined by the data dependance check circuit. A set of register file port multiplexers select the tags generated by the tag assignment circuit and pass the tags onto the read address ports of the register file for storing execution results.

摘要： Tag monitoring system for assigning tags to instructions. A memory unit stores instructions to be executed by an execution unit. Before execution an instruction fetch unit decodes the instructions. A register file stores the decoded instructions. A queue having a plurality of slots containing tags which are used for tagging the decoded instructions. A control unit assigns the tags to decoded instructions, monitors the completion of executed instructions, and advances the tags in the queue upon completion of an executed instruction. The register stores a given decoded instruction at an address location in the register file defined by the tag assigned to that instruction. The register file also contains a plurality of read address enable ports and corresponding read output ports. Each of the slots from the queue is coupled to a corresponding one of the read address enable ports. Thus, a a decoded instruction is read out of a read output port enabled by the tag assigned to that decoded instruction in program order.

摘要： An integrated structure layout of functional blocks and interconnections for an integrated circuit chip. Data dependency comparator blocks are arranged in rows and columns. This arrangement defines layout regions between adjacent ones of the data dependency comparator blocks in the rows. Tag assignment logic blocks are coupled to the data dependency comparator blocks to receive dependency information. The tag assignment logic blocks are positioned in one or more of the layout regions so as to be integrated with the data dependency comparator blocks to conserve area on the semiconductor chip and to spatially define a channel in and substantially orthogonal to one or more of the rows. Register file port multiplexer blocks are coupled to output lines of the tag assignment logic block adjacent to the orthogonal channel to receive tag information and to pass the tag information to address ports of a register file.
