VERTEX PROCESSING APPARATUS AND METHOD HAVING MULTI-STAGE PIPELINE STRUCTURE

摘要

A device and a method for processing a vertex in a multi-stage pipeline structure are provided to reduce the maximum delay between respective execution codes to three stages by using an ALU(Arithmetic Logic Unit) of the multi-stage pipeline structure sequentially connecting operators. A first resister(310a) stores data for processing the vertex and a second register stores an operating result. An instruction fetch unit(300) sequentially fetches an instruction including an OP(Operation) code and more than one operand. A decoding unit(320) decodes the instruction and reads the needed data from the first register according to the operand. The ALU(330) comprises a plurality of operators, and sequentially processes/outputs the data through more than one operator according to a type of the OP code. A write back unit(340) stores an operation result of the prior OP code to a second register(310b) and temporally stores other results in the inside to process other result in the next stage.
