Abstract

The invention relates to the technical field of computer teaching experiments and discloses a device and a method of remote VGA (video graphics array) display used for computer hardware experiments. The device comprises an experimental FPGA (field-programmable gate array), a shared SRAM (static random access memory), a control FPGA, a server and a client terminal, wherein the experimental FPGA is used for acquiring information necessary for VGA display, the control FPGA is used for reading data which are send from the experimental FPGA to the shared SRAM, and the shared SRAM is used for data access of the experimental FPGA and the control FPGA. The invention also discloses a method for performing remote VGA display by virtue of the device. According to the invention, the information in VGA signals are divided into two output parts in which one part is outputted to the shared SRAM, then the control FPGA reads data from the shared SRAM and transmits the data to the client terminal, as a result, the VGA signals from the experimental FPGA can be displayed on a remote experimental platform.

Description

technical field [0001] The invention relates to the technical field of computer teaching experiments, in particular to a remote VGA display device and method for computer hardware experiments. Background technique [0002] A big problem with the remote unified experimental platform is that the hardware description language written by the experimenter forms its own hardware, but if there is a need for VGA output, the remote unified experimental platform has no way to accept the VGA signal output by the experimental FPGA. This brings a lot of trouble to remote debugging. In this case, the remote has no way to see whether its own VGA output is correct, or, in the case of graphic interaction, such as playing chess, entering a password, etc., there is no way to see the situation on the remote VGA. Contents of the invention [0003] (1) Technical problems to be solved [0004] The technical problem to be solved by the invention is: how to enable the remote experiment platform ...
