Hello Dear Reader, Here in this post, I will give an idea about how we can design microprocessors from the scratch as per the requirement. When designing a new microprocessor or microcontroller unit, there are a few general steps that can be followed to make the process flow more logically. These few steps can be further sub-divided into smaller tasks that can be tackled more easily. The general steps to designing a new microprocessor are: Determine the capabilities the new processor should have. Layout the datapath to handle the necessary capabilities. Define the machine code instruction format (ISA). Construct the necessary logic to control the datapath. Let's see each in details: Determine Machine Capabilities: Before you start to design a new processor element, it is important to first ask why you are designing it at all. What new thing will your processor do those existing processors cannot? Keep in mind that it is always less expensive to utilize an existing chip than to des
