CONTROL SCHEME FOR BINARY CONTROL OF A PERFORMANCE PARAMETER

摘要

The present invention relates to a control system and method of controlling at least one performance parameter of an integrated circuit. The at least performance parameter is controlled based on a control word. However, the signaled control information is reduced to a binary control signal simply instructing increase or decrease of said at least one performance parameter. This is achieved by modifying the control word in accordance with the binary control signal, e.g., by using the binary control signal to define a binary value shifted into a shift register means (31). Thereby, a fast and simple control functionality can be provided, which does not require any further hardware to adjust the performance parameter.
