Abstract
A first-in-first out (FIFO) register 100 for storage of up to two-bytes of data is operable by two control units 10, 20 for simultaneous read and write operations with no wait states. The FIFO register 100 comprises a first register 101, a second register 102 and a controller U35. The first register 101 may be multplexed between the two control units 10, 20 for write operations by either unit. The second register 102 is in communication with the first register 101 and may be read by either control unit 10, 20. Data is transferred from the first register 101 to the second register 102 under the direction of the controller U35 such that data may be read by one control unit 10, 20 while data is being simultaneously written by the other control unit 10, 20.
