Embodiment Construction

[0022] In order to describe the present invention more clearly, below in conjunction with accompanying drawing and embodiment, specific embodiment of the present invention is described in further detail:

[0023] like figure 1 Shown, a kind of FPGA loading method provided for the embodiment of the present invention, comprises:

[0024] S100, loading part of the content of the FPGA;

[0025] Only part of the content is loaded, and the FPGA cannot complete the inspection of the loaded content. The power consumption of the FPGA is basically the same as the erase state, and it is in a low power consumption state.

[0026] S102, monitor whether the FPGA needs to be used, if yes, jump to S104, if not, continue monitoring;

[0027] Whether the FPGA needs to be used can be monitored by the CPU, and if it is not needed, continue monitoring, keep the state of S102, and jump to S104 if it needs to be used.

[0028] S104. Load remaining content of the FPGA.

[0029] After detecting th...

Abstract

The invention discloses a method for loading an FPGA (Field Programmable Gate Array), which comprises the following steps of: loading part of content of the FPGA, wherein the checking of the loaded content can not be completed by the FPGA at the time; monitoring whether the FPGA is necessary to utilize; and if so, loading the remaining contents of the FPGA. The invention also discloses a device for loading an FPGA. Before the FPGA is necessary to utilize, only part of content is loaded by the FPGA, and the power consumption of the FPGA at the time is very less; when the FPGA is monitored to utilize necessarily, only the remaining contents of the FPGA are necessary to load, and the loading can be completed within very short time, therefore, the power consumption of the FPGA is reduced under the condition of having no influence on the efficiency.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to an FPGA loading method and device. Background technique [0002] A Field Programmable Gate Array (Field Programmable Gate Array, FPGA) has programming flexibility and high-speed hardware, so it is more and more widely used. With the development of semiconductor technology, the integration level of FPGA is getting higher and higher, and the power consumption of FPGA is also increasing. [0003] With the continuous progress of society and the continuous development of science and technology, people now fully realize the importance of the environment to human development. All countries are taking active and effective measures to improve the environment and reduce pollution. The most important and urgent issue is energy. The problem, in addition to finding new energy sources, energy saving is the key and the most direct and effective important measure at present. [0004] The p...
