    • An instruction compressing apparatus and method for a parallel processing computer such as a very long instruction word (VLIW) computer, are provided. The instruction compressing apparatus includes a bundle code generating unit, an instruction compressing unit, and an instruction converting unit. The bundle code generating unit may generate a bundle code in response to an input of instructions to be compressed. The bundle code may indicate whether a current instruction group is terminated, and also whether an instruction group following the current instruction group is a no-operation (NOP) instruction group. The instruction compressing unit may remove a NOP instruction and/or a NOP instruction group from the input instructions according to the generated bundle code. The instruction converting unit may include the generated bundle code in the remaining instructions which have not been removed by the instruction compressing unit.
    • 提供了一种用于并行处理计算机例如非常长的指令字(VLIW)计算机的指令压缩装置和方法。 指令压缩装置包括束代码生成单元,指令压缩单元和指令转换单元。 捆绑代码生成单元可以响应于要压缩的指令的输入而生成捆绑代码。 捆绑码可以指示当前指令组是否终止,以及当前指令组之后的指令组是否是无操作(NOP)指令组。 指令压缩单元可以根据所生成的包代码从输入指令中去除NOP指令和/或NOP指令组。 指令转换单元可以包括尚未被指令压缩单元去除的剩余指令中的生成的捆绑代码。
