His innovative approach has led to the development of a unique patent that addresses critical issues in tag checking.

Latest Patents

Langlois holds a patent for a technology that involves remapping at least one of a guard tag and an address tag associated with a target address to generate a remapped tag for use in tag checking. The apparatus he developed includes tag checking circuitry that is responsive to a target address. It identifies a guard tag stored in a memory system in association with a block of memory locations. This block contains a target memory location identified by the target address. The system performs a tag check based on the guard tag and an address tag associated with the target address. In the event of a mismatch during the tag check, the system executes an error response action. Additionally, the apparatus features tag mapping storage circuitry that stores mapping information indicative of a mapping between guard tag values and corresponding address tag values. The tag checking circuitry remaps at least one of the guard tag and the address tag based on the stored mapping information to generate a remapped tag for use in the tag check.
