Communication processor

Abstract

Abstract PURPOSE:To attain efficient data transfer by providing the titled processor with plural processing request control means. CONSTITUTION:A serial/parallel (S/P) data conversion means 31-1 receives serial data on a line, converts the serial data into parallel data, and when the means 31-1 can be allowed to inform the parallel data to a processor means 10 or can be allowed to prepare the reception of transmission data from the means 10, commands an identification (ID) number sending means 30-1 to send the ID number. A processing request managing means concerned out of plural means 20-1-20-M stores a processing request sent from the means 30-1 and generates an interruption to the means 10. Respective means 20-1-20-M store ID numbers sent from respective ID number sending means 30-1-30-N by a first-in first-out method and extract these numbers. At the time of receiving said interruption, the means 10 sends an interruption receiving signal to the means 20-1-20-M.
