Title:
駆動電力ゲーティングの応用
Document Type and Number:
Japanese Patent JP5725582
Kind Code:
B2
Abstract:
Systems and methods are disclosed to manage power in a custom integrated circuit (IC) design by receiving a specification of the custom integrated circuit including computer readable code and generating a profile of the computer readable code to determine instruction usage; automatically generating a processor architecture uniquely customized to the computer readable code, the processor architecture having one or more processing blocks and one or more power domains; determining when each processing block is needed based on the code profile and assigning each block to one of the power domains; and gating the power domains with power based on the code profile; and synthesizing the generated architecture into a computer readable description of the custom integrated circuit for semiconductor fabrication.
