Abstract
PURPOSE: To perform access to the memory unit with less number of strobe signal lines, by separating the strobe signal delivery lines into those for memory unit and for input and output module, and performing skew compensation to the input and output module.
CONSTITUTION: The constitution of the bus line 4 of the information processing unit consisting of CPU1, memory unit 2, and input and output modules 3-1 and 3-2, is separated into the address read-in/write-in line 4a, data line 4b, strobe signal delivery line 4c, memory unit strobe signal delivery lime 4cm, and input and output unit strobe signal delivery line 4ci. The CPU 1 with this constitution is provided with the skew compensation unit 1a performing skew compensation to the signal delivery line 4ci to compensate the skew to the modules 3-1 and 3-2. The access time to the memory unit 2 is avoided from being affected with the number of the modules 3-1 and 3-2, and the connection of many modules is enabled by reducing the number of the strobe signal lines.
