An execution migration approach includes bringing the computation to the locus of the data: when a memory instruction requests an address not cached by the current core, the execution context (current program counter, register values, etc.) moves to the core where the data is cached.

Execution migration

A system and method for Term Rewriting System hardware design employs a scheduler that incorporates a preference order in scheduling conflicting rules. The scheduler schedules a conflicting rule to execute when its predicate is true, and it is preferred over other conflicting rules in the preference order. The preference order may be, in one embodiment, a user-specified preference order enumerated by a designer. Such an order may be chosen according to efficiency criteria, such that the conflicting rule most essential for efficient hardware will be scheduled to execute on a given state rather than less essential conflicting rules The system and method advantageously permits a schedule to be computed in a time frame polynomially related to the number of rules, and produces more predictable and more easily understood schedules than conventional methods.
