Abstract
Abstract A data flow type information processor includes a program storing portion, a paired data detecting portion, an operation processing portion, an internal data buffer, and an external data memory. A data packet processed in the program storing portion, the paired data detecting portion and the operation processing portion is transferred to the internal data buffer. On the other hand, a data packet outputted from the external data memory is transferred to another information processor through a merge portion, a branch portion, another merge portion and another branch portion. Thus, internal processing through the internal data buffer and processing from the external data memory to the exterior are not merged.
