Show examples of C code that explicitly do a read-modify-write operation on SAMD21 I/O pin PA02 to setthis bit in a PORT register, clear it in a PORT register, and toggle it in a PORT register. You may assumeit has already been initialized as an output. If possible, show an example of code that implicitlydoes a read-modify-write operation on this pin.

The class I'm taking is physics for scientists and engineers! Need help. I have attached the problem.  Thank you so much!

I get an error in LC3 assembly programming when i try to run this code. can someone explain how i can fix this and give me the solution to the fix. i will be very thankfull

If you have an architecture which has base and bound registers where there is one base register and one bound register per program, is it possible to have two programs share data?

Suppose you wanted to implement a control unit for a computer that you are designing. A. Would you use a hardwired implementation or a micro-programmed control unit?  Why?   I would use a micro-programmed control unit for my computer. The reason for this is because micro-programmed control units are easier to handle and make modifications. Also, modern processors that utilize the CISC architecture can convert code to be more RISC-like to be used internally. B. What factors in the computer design would affect your decision?   It depends on my intended plan for the device. If I were to design a personal computer for non-commercial use, I would more than likely implement micro-programmed control units. If I were to design microprocessors for use in embedded systems or mobile devices, I would use the hardwired control unit.

I asked the question before and the answer I got does not makes sense.  My question is why did not we considered the Adder, Shift, ANd, Control when calculation delay time.? Again, it is in Risc-V.

You must write MIPS assembly code which will read an integer from the user, and will then print (in order): The integer A newline character The negation of the integer (with the help of the nor instruction) A newline character Example output of this code is shown below, where 63 was the input integer: 63 -64

Instruction opcode  please help me finish the diagram fill the number of "?" If my diagram is something wrong, please modify it.

We can design stack architectures, accumulator architectures, or general-purpose register architectures. Explain the differences between these choices and give some situations where one might be better than another.
