Data driven computer producing inhibit signal for inhibiting merging external provided data pieces with internal data pieces when number of processing data exceeds reference value

摘要

In a data-flow type computer using paired data, the improvement of a data transmission apparatus wherein the difference in the number of data pieces written in a memory and the number of data pieces read out from the memory is determined. If this difference exceeds a predetermined number, a transmission inhibiting signal is generated from an inhibiting signal generating portion to be applied to a merging portion, wherein the merging portion temporarily inhibits the merging of data from an external data memory or external information processing unit and then allows for the merging of data when the difference becomes less than the predetermined number.
