Abstract
This asynchronous processor core comprises a loading unit for sequentially loading instruction lines, functional units for executing instructions and a decoder for decoding instruction lines loaded by the loading unit into instructions executable by the functional units. It comprises an execution control module configured as a two-state automaton: a sleep state (S), wherein the asynchronous processor core awaits an interrupt control signal to execute an interrupt routine; an execution state (S), wherein the decoder awaits a new interrupt routine instruction line to be decoded. The execution control module additionally manages a state variable (status) of the loading unit to selectively authorize or prevent, according to at least the value of this state variable (status), the loading of a new instruction line.
