Logic circuit module having power consumption control interface and a recording medium storing the module
View Patent ↗Consumption power control is provided for a system LSI made of a combination of a plurality of reusable logic circuit modules, i.e., Intellectual Property (IP) cores. Hardware resources such as interfaces and registers for the consumption power control of other IP cores are prepared and controlled by software for the consumption power control of a system LSI. The consumption power can be controlled at an IP core level. A method is provided which facilitates a system LSI designer to enter a consumption power control specification of a system LSI when the system LSI is configured.
1. A logic circuit constituting a power module, comprising:
a built-in main processor;
an interface for performing power consumption control; and
a function controlling consumption of power on another power module,
wherein said another power module includes an interface for outputting a request for raising or lowering an amount of power consumption of the logic circuit.
2. The logic circuit having a built-in main processor according to claim 1 , wherein the logic circuit further includes a clock signal output interface and said interface.
