PROBLEM TO BE SOLVED: To provide a bus system that makes a memory-logic conjugate system function at high speed and with low power consumption.SOLUTION: Provided is a bus system for connecting functional blocks in a block chip with each other, with a plurality of functional blocks functioning as a memory circuit and/or a logic circuit arranged in array form in the block chip. The bus system includes an output control unit for controlling the destination of a data signal outputted from a functional block. The output control unit has an AND circuit 31 and a switch circuit 32. A clock signal and a selection signal are inputted to the AND circuit 31. The switch circuit 32 makes the data signal outputted via a first adjacent bus 33 when the AND circuit 31 is off, and makes the data signal branched off and outputted via the first adjacent bus 33 and a second adjacent bus 34 when the AND circuit 31 is on.SELECTED DRAWING: Figure 5 |
