A microprocessor system

A microprocessor system

Like any other system, a microprocessor has inputs, outputs and a process as shown in Figure 1.4. The inputs and outputs of a microprocessor are a series of voltages that can be used to control external devices. The process involves analysing the input voltages and using them to ‘decide’ on the required output voltages. The decision is based on previously entered instructions that are followed quite blindly, sensible or not.
