Title: Dual lane computing system
Inventor: FITZPATRICK ROGER SEAN
IPC: G06F11/25
Filed: 1992-10-08
Abstract: The computing system has at least one processor (2,3) in each lane, each processor having an associated memory (18,19) which stores input data supplied to the processor and the time of arrival.
