Abstract

The invention discloses a power control method and device for a programmable logic device and electronic equipment. The method comprises the steps of: determining a function module set in the programmable logic device, and enabling the function module set to comprise a plurality of function modules; and controlling the function modules in the function module set to reset or de-reset in batches under the condition that a reset instruction or a de-reset instruction is received. According to the implementation scheme, when the programmable logic device needs to be reset or de-reset, all the function modules in the programmable logic device are reset or de-reset in batches, so that transient current pressure generated when all the function modules are reset or de-reset in a centralized manner is dispersed, the service life of the programmable logic device is effectively prolonged, and normal use by a user is ensured.

Description

technical field [0001] The present application relates to electrical control technology, and more specifically, relates to a power control method, device and electronic equipment of a programmable logic device. Background technique [0002] In order to provide continuous and efficient services, some base stations and data centers will use accelerator cards, such as FPGA (Field Programmable Gate Array, a semi-custom circuit in ASIC, which is a programmable logic array) chip, to increase data processing speed . When designing FPGA code, resetting or unresetting all functional modules at the same time will generate a large transient current, resulting in FPGA voltage overshoot or voltage undershoot, causing permanent damage to FPGA or causing its function to be abnormal, affecting users normal use. Contents of the invention [0003] In view of this, the application provides the following technical solutions: [0004] A power control method for a programmable logic device, ...
