Title: Device for and method of adapting dual-port memory between network adaptor and central control device
Inventor: KIM HYON-KI
IPC: G06F13/38
Filed: 1991-12-17
Granted: 1994-10-13
Abstract: The apparatus for reducing the necessary peripheral devices for connection and increasing the speed of the information exchange includes a first and a second dual port memories(30,40) common-used by a network processor and the CPU, memory allocators allocating the memory zone and controlling the read/write of the memory, data transfer controllers determining the data flow direction, and a data determining circuit discriminating the 8 bit signal applied to the memory to the upper or lower 8 bit data.
