I want to ask if it is a lot of work to implement a calculator with a decimal formula [Copy link]

The matrix keyboard inputs a four-digit decimal number x, and through a formula (such as y=0.2x), the four-digit decimal number y is input on the digital tube. Is it feasible? Is the workload too large?

If it's too difficult, three or two people, or is there any alternative solution?

A newbie, using CPLD

Thank you all

Output on the digital tube, wrong

51 single chip microcomputer can do it, and all LCD displays

The workload is not much greater when using CPLD

Look at your own algorithm

For qualified engineers, the workload is not large. But for beginners, the amount of learning is the key. The amount of learning is determined by your current relevant knowledge structure, ability, and understanding, which is a completely different matter.

The price of CPLD is definitely more expensive than that of MCU! As long as it can drive the digital tube (diode) and the number of pins meets the requirements, there are many such MCUs, and the cost can be done with a few yuan!

Wouldn't it be easier to use a multiplier IP core?

It is recommended to do some experiments related to clock/frequency. The cpld/fpga timing is the feature
