Abstract From the Canadian patent

This invention relates to fault-tolerant computer systems. Bus interface units (BIUs) perform fault detection identification, and reconfiguration for all information transfers between redundant central processing units (CPUs) and memory or input/output (I/O) in a mesh interconnected array of a computer system. Errors are detected by self- checking within the BIUs signal parity checks by the BIUs, cross channel comparisons and mesh transaction assessments. If self implicating errors are detected the corresponding BIU is shut down, BIU configuration vectors are asserted onto the mesh and a consensus configuration vector is generated. If synchronization or memory bus errors are detected …

Why it's free to use

  • Filed June 3, 1997 and granted November 25, 2003. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended June 3, 2017.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 3, 2019.
  • We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
