Abstract
A data driven type information processor includes a control unit having a function of storing a data flow program and accessing it, and a function of producing an operand data pair, the control unit further including one memory shared by both functions. When a program is executed, program data per 1 accessing to the memory and operand data related to the program data are read out simultaneously and applied to an operation unit. Accordingly, a program memory and a memory for queuing operand data, which, were separately provided in a conventional technique, are combined into a single mechanism. Thereby, the number of stages of processing in program execution in the information processor is reduced and increase in program execution speed is permitted.
