Abstract

PURPOSE: To perform high-speed information-by-information transmission from the memory part of a queue circuit by reducing hardware in size by eliminating the cutting of information in process of transfer due to a difference in processing performance between processors.
CONSTITUTION: From 1st processor 1 to 2nd processor 2, information is transferred via queue circuit 3. At the input side of memory part 31 of this queue circuit 3, gate circuit 35 is arranged and at the input side of circuit 35, buffer circuit 36 is further arranged to store this circuit 36 with transfer information, piece by piece, temporarily. Then, information transferred from processor 1 is stored, piece by piece, in circuit 36 and control circuit 32 exercises control over the high-speed transfer of this information to memory part 31 by opening gate circuit 35. While the information is in process from circuit 36 to memory part 31, a busy signal is sent to signal line 33 to queue next information and after the information is stored in memory part 31, a process request signal is sent from signal line 44 to transfer information to processor 2.
