Variable frequency controller, control method, chip, equipment and storage medium

Abstract

The embodiment of the invention provides a frequency conversion controller, a control method, a chip, equipment and a storage medium. The frequency conversion controller comprises a firmware access storage module configured to be used for storing frequency conversion firmware; the frequency conversion management module is connected with the firmware access storage module and is configured to be connected with a system control module of the system-on-chip so as to receive a frequency conversion request signal and target frequency information sent by the system control module, retrieve frequency conversion firmware according to the frequency conversion request signal and send the frequency conversion firmware to the system control module; determining a frequency conversion instruction for the dynamic random access memory based on the frequency conversion firmware and the target frequency information; and the frequency conversion execution module is connected with the frequency conversion management module and is configured to execute the frequency conversion instruction. The frequency conversion controller can replace the system-on-chip in the system-on-chip to take over the frequency conversion operation of the dynamic random access memory, dynamic frequency conversion can be achieved, the frequency conversion process does not need too much participation of the system control module, and resources of the system control module are greatly saved.

Description

technical field [0001] The present application relates to the technical field of integrated circuits, and in particular, the present application relates to a frequency conversion controller, a control method, a chip, a device, and a storage medium. Background technique [0002] As the design scale of SoC (System on Chip, system-on-chip) becomes larger and larger, the dynamic power consumption is also higher and higher, and reducing the clock frequency when necessary can effectively reduce the dynamic power consumption. [0003] The SoC chip includes several sub-module device structures, such as DDR (full name DDR SDRAM, Double Data Rate SDRAM, double-rate synchronous dynamic random access memory) DRAM subsystem is an important module of the SoC chip, and its power consumption will affect the SoC chip. Power consumption has a more obvious impact. [0004] However, related technologies of the DRAM subsystem have defects such as difficulty in realizing dynamic frequency conver...
