Abstract:
1. An information communication system for performing information communication between a first system and a second system, comprising: a first communication path that is used for information communication when a transfer size between the first system and the second system is smaller than a predetermined size and is capable of high-speed response when the transfer size is smaller than the predetermined size; and a second communication path that is used for information communication when the transfer size between the first system and the second system is larger than the predetermined size and has a larger transfer capability than that of said first communication path when the transfer size is larger than the predetermined size; wherein each of the first and second systems comprises main control means for selectively using one of said first and second communication paths in accordance with a size of information subjected to information communication with a counterpart system; an internal bus connected to said main control means; first interface control means for sequentially performing information communication with the counterpart system through said first communication path under the control of said main control means in its system through said internal bus; and second interface control means for performing information communication with the counterpart system through said second communication path independently of said main control means in accordance with an instruction from said main control means in its system, wherein the information communication by the second interface control means is performed without using the internal bus.
