The AHB Low Power Subsystem is an AMBA® based system that is useful as the basic digital infrastructure for building low power SOCs. The subsystem contains a flexible Power Management Unit that controls the power sequence of the CPU as well as the APB peripherals. The PMU can easily be extended to control additional cores, peripherals and even mixed signal subsystems on the same SOC.
The AHB Low Power Subsystem includes a standard set of peripherals and cores that supports RTOS and software kernels. The package includes software for boot code, interrupt handlers and driver code.
The AHB Low Power Subsystem is soft IP that can be used in all the popular semiconductor technology nodes.
