Token-based current control to mitigate current delivery limitations in integrated circuits

摘要: A system and method of operating an integrated circuit (IC) having a fixed layout one or more blocks current sources therein that draw electrical from power source. The includes dynamically issuing to block configured perform operations responsive instruction received at the block, reserve amount tokens; determining for each issuance whether block's token exceeds zero; of: if is greater than one, decrementing, after instruction, by amount, or, preventing block. In method, may be initialized have: zero, expiration period; generation cycle amount.
