Yes. Most early microprocessor in the 70's were NOT microcoded. Microcoding takes a lot of real estate on the silicon and the trade-off was not worth it until the chip densities increased in the 80's. I worked on two microcoded microprocessor 1972-73 for American MicroSystems Inc (AMI), called the 7200 and the 7300. Both worked quite well but were large chips. Had it not been for AMI making the decision that "there is no future in microprocessors" both the 7200 and 7300 would have succeeded. Both were well documented from talks at trade shows.

What is the need for timing diagram in microprocessor?

The need for a timing diagram for a microprocessor is, primarily, to allow you to properly design the interface logic that will support the microprocessor. You need to know what lines are used to execute various data transfers, what are the timing of those lines with respect to each other, and how the microprocessor expects the external logic to behave. You can also use the timing diagram to understand how the microprocessor functions and, particularly, to know how long each instruction will take.


Why 7 segment display is used in microprocessors?

A 7 segment display is an I/O device, and it is not necessarily used in microprocessors. The choice of I/O devices is a function of system design, not microprocessor design.

What is the purpose of a software model of a microprocessor?

Typically, a software model of a microprocessor describes the microprocessor in a register transfer language (RTL). To test the software model, a set of test instructions, referred to as a "test case," is written in the machine language of the microprocessor, and a simulator simulates the execution of those instructions by the microprocessor. Software verification tools compare the results obtained from the simulation with the results that should be obtained if the microprocessor is functioning correctly. If the expected results do not match the actual results, an error exists in the design. In response, the software model may be modified in an attempt to rectify the identified error.
