PURPOSE:To access an operand easily and quickly, by providing a memory where a queuing operand for parallel control are stored, and providing a succeeding address to be searched at the end of the queuing operand. CONSTITUTION:In a data flow type processing device, each time a procedure is called, a new tag is generated, and an operand is added. Queuing operands for parallel control are stored in an operand memory 106 provided independently of an instruction memory 105. The operand memory 106 is accessed by the pointer from the instruction memory 105. The address having a succeeding operand to be searched is provided at the end of each operand, and operands are arranged in a chaining structure. The chain is traced to find tags; and thus, the arrangement of the operand memory has tolerance, and the use rate of the memory is improved, and operands are accessed quickly. |
