HIGH INTEGRITY AND HIGH AVAILABILITY COMPUTER PROCESSING MODULE

摘要

A high-integrity, N-lane computer processing module (Module), N being an integer greater than or equal to two. The Module comprises one Hosted Application Element and I/O Element per processing lane, a Time Management unit (TM) configured to determine an equivalent time value for a request made by software running on each of the N processing lanes, irrespective as to when the request is actually received and acted on by each of the N processing lanes, and a Critical Regions Management unit (CRM) configured to enable critical regions within the respective lane to be identified and synchronized across all of the N processing lanes.
