Problems solved by technology

The conversion between the control signals generated by the above two kinds of microprogram controllers and the control signals generated by the combination logic controller needs to be completed when the power supply is not powered on, and cannot be operated with power on; the microprogram controller can be generated by rewiring. The conversion between the control signal and the control signal generated by the combinatorial logic controller increases the unreliability of the experimental setup due to the nature of its physical plug-in

Abstract

The invention relates to a computer theory tester which can convert control signal in one time, belonging to computer teach tester technical field. The invention comprises a math logic elements, an accumulator, a first, a second, and a third registers, a tri-state door, a data switch, a memory, a convert switch, a selector for selecting one of first and second registers, a program counter, an address counter, a command register, an operand decoder, a sequence timer, a micro program controller, and a combined logic controller. The invention has the advantages that the invention can meet the computer theory tester of micro program controller and logic controller, while user can dial a dual-bit switch to switch between micro program controller and combined logic controller.

Description

technical field [0001] The invention relates to a computer composition principle experiment device for one-time full conversion of control signals, which belongs to the technical field of computer teaching experiment instruments. Background technique [0002] The principle of computer composition is a very important basic course in universities. At present, there are several kinds of experimental devices on the principle of computer composition in the market, such as the TEC-5 computer composition and combinatorial logic experiment system produced by Tsinghua University Scientific and Educational Instrument Factory. Its structural block diagram is shown in Figure 1. The structure block diagram of the TDN-CM++ computer composition and system structure teaching experiment system produced is shown in Figure 2. The principle of computer composition The experimental device usually includes four parts: sequential circuit, memory, arithmetic unit and controller; the control signal...
