Coupling device for e.g. data processing arrangement, has cache memory receiving and storing data received in serial data format via serial interface, and transmitting data stored in cache memory to parallel interface

摘要

The device (103) has a serial interface (110) for receiving data, and a parallel interface (114) for transmitting data. A cache memory (104) is coupled to the serial and parallel interfaces. The cache memory is provided to receive and store data received in a serial data format via the serial interface, and to transmit data stored in the cache memory to the parallel interface. The parallel interface comprises a parallel data bus (112) and parallel address bus (111). A buffer memory is coupled with the serial and parallel interfaces. An independent claim is also included for a method for transmitting data from a memory.
