Abstract
A data transmission system between two system buses and a method therefor are capable of bi-directionally transmitting data between two bus systems whose word widths are different. The data word from a first system bus is converted to a data word width of a second system bus, and the converted data is outputted to the second system. The data word from the second system bus is converted to a data word width of the first system bus, and the converted data is outputted to the first system. The data transmission system includes first and second system interfaces, first and second FIFO buffers, first and second FIFO controllers, first and second latches, and first and second selectors correspondingly coupled between the first and second system buses to allow bi-directional transfer of data.
