Apparatus and method for dispatching very long instruction word having variable length |
摘要 |
Apparatus and method for dispatching a very long instruction word (VLIW) instruction having a variable length are provided. The apparatus for dispatching a VLIW instruction includes a packet buffer for storing at least one or more VLIW instructions, and a decoding unit configured to constitute a VLIW instruction to be currently executed among the VLIW instructions stored in the packet buffer and decode predetermined bits of each sub-instruction contained in the VLIW instruction. The apparatus dispatches a corresponding sub-instruction to an FU which corresponds to each sub-instruction, based on the results of decoding performed in the decoding unit, position information on the sub-instructions that are placed on the packet buffer, and position information on the sub-instructions that are placed in the current VLIW instruction. Sub-instructions can be effectively dispatched to corresponding FUs using simple decoding logic even in a case where the length of the VLIW instruction is not fixed.
