摘要： In the case of constituting a processing unit having the characteristic of a VLIW type processing unit and the characteristic of a pipeline type processing unit, since reference to the result of operations is made among a plurality of processing units executing in parallel the operations, transfer of the register file is frequently generated among the processing units, resulting in insufficient effect of the high speed operations. In view of solving this problem, the predicate registers are provided and moreover a means for broadcasting the update data of the predicate register to all processing units is also provided. Thereby, operations for obtaining branching condition and numerical value can be realized in different processing units and the number of steps of the processing program can be reduced. In addition, since high speed transfer between the processing units of the data register having a wider bit width is no longer required and thereby the mounting area can be reduced and high speed processing unit can be realized.
摘要翻译：在构成具有VLIW类型处理单元的特征的处理单元和流水线类型处理单元的特性的情况下，由于在并行执行操作的多个处理单元中进行操作结果的参考，因此，在处理单元之间经常生成寄存器文件，导致高速操作的效果不足。为了解决这个问题，提供了谓词寄存器，并且还提供了用于向所有处理单元广播谓词寄存器的更新数据的装置。因此，可以在不同的处理单元中实现获得分支条件和数值的操作，并且可以减少处理程序的步数。此外，由于不再需要具有较宽位宽的数据寄存器的处理单元之间的高速传输，从而可以减小安装面积，并可实现高速处理单元。

摘要： Each processing unit 110a to 110d has an individual cache memory 100a to 100d. When the cache memories read an instruction from a main storage 5, an instruction field is distributed to the cache memories. Each cache memory is controlled by a common control circuit 20. A compiler operates to schedule the processes so as to focus the processes to be executed on a specific processing unit. According to the scheduled processes, the volumes of the cache memories 100a to 100d are specified according to each execution ratio of the corresponding processing units to the cache memories. In the foregoing arrangement, a processor provides the processing units controlled by a sole program counter and improves processing by improving the efficiency of the cache memory. Further, the processor improves the efficiency of the cache memory by deleting unnecessary codes.
