[Other] Computer composition principle decomposition experiment: Experiment three-binary complement Calculator

Purpose:

Purpose:

You can understand the data stream and its time sequence relationship based on the model of the complement calculator.

Measure the test taker's knowledge about the basic principles of the addition and subtraction operations of the adder.

Devices and instruments used in the experiment:

The accumulators use 74LS273.

The divider uses two 74 ls283 pieces.

The original anti-code controller uses 74ls86.

Use 74ls86 for overflow determination.

Lab content:

◆ The data width is 4 bits, and an experimental circuit diagram is designed.

◆ Design test steps.

◆ Use the switch to load data and complete code addition and subtraction.

◆ The symbol bit operation adopts dual-symbol bit. The accumulators should be reset.

◆ Observe the computation result with the indicator light, record the experiment phenomenon, and write the experiment report.
