Claim 4:
5. The method according to claim 1, wherein checking if an ALU pipeline targeted by a decoded instruction from a scheduled task in an active state is full by checking a value of an ALU work fullness counter associated with the targeted ALU pipeline comprises:
checking if an ALU pipeline targeted by a decoded instruction from a scheduled task in an active state is full by checking a value of both an ALU work fullness counter and a de-activated scheduled tasks counter associated with the targeted ALU pipeline;, and wherein the method further comprises:
in response to determining that the targeted ALU pipeline is full, updating the de-activated scheduled tasks counter associated with the targeted ALU pipeline; and
after triggering the scheduler to re-activate an oldest scheduled task waiting for the ALU pipeline by removing the oldest scheduled task from the waiting state, updating the de-activated scheduled tasks counter associated with the ALU pipeline.
