Abstract
A data bus width conversion apparatus is provided for receiving N-bit data from a first device having a first bus width and outputting the N-bit data to a second device having a second bus width. The first device divides the N-bit data into a plurality of bit data groups and the plurality of bit data groups are transferred to the apparatus. The apparatus comprises a setting section for setting the total number of transfer operations required for the first device to transfer the plurality of bit data groups, and for setting a division pattern of the N-bit data for dividing the N-bit data into the plurality of bit data groups, a receiving section, and an output section for producing the N-bit data from the received data indicated by each of the plurality of bit data groups and outputting the produced N-bit data to the second device.
