Embodiment Construction

[0028] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not constitute a conflict with each other.

[0029] The core 8086CPU part of the experimental platform of the present invention is described in VHDL language and implemented inside the FPGA chip. The whole FPGA is equivalent to an 8086CPU, but the UART core is also integrated in the FPGA chip, so that the FPGA is an independent operating system. Microcomputer, based on this independent microcomputer, various microcomputer principle experim...

Abstract

The invention discloses an FPGA-based microcomputer interface hardware experiment platform. The experiment platform includes a core circuit, an interface circuit and a peripheral circuit; the core circuit includes an FPGA chip, an FPGA configuration chip and a crystal oscillator, the FPGA chip is used for realizing the functions of a 8086CPU, the FPGA configuration chip is used for storing configuration information of an FPGA, and the crystal oscillator is used for providing an FPGA clock signal; and the FPGA chip includes a 8086CPU core, an UART core, an ROM and an SRAM, the UART core is used for serial port communication, the ROM is used for an instruction jump to the SRAM after electrification, and the SRAM stores run programs which all adopt VHDL hardware description language to compile. The FPGA-based microcomputer interface hardware experiment platform having complete functions of the 8086CPU not only supports routine microcomputer principle and interface experiments, but also supports advanced experiments such as an operating system loading process and BIOS programming.

Description

technical field [0001] The invention relates to the technical field of microcomputer interface, in particular to a microcomputer interface hardware experiment platform, which satisfies the experimental requirements of students in the Microcomputer Principles and Interface Course. Background technique [0002] The course "Principles and Interfaces of Microcomputers" is an important professional core course of computer science in many colleges and universities in China. The quality of the experimental platform has a great influence on students' real mastery of microcomputer principles and interface technology. [0003] From a technical point of view, the experimental platforms of "Principles and Interfaces of Microcomputers" currently on the market mainly include the following four types: (1) Using software to simulate the hardware environment, the operation process for students to experiment in the virtual environment. (2) The test box is driven by the PCI bus or ISA bus of ...
