Explain what the ARM instruction LDMFD sp!, {r1,r3,r5} does.

If an instruction is not accepted and it writes to VA page 30, what will happen? A TLB that is handled by software would perform better than a TLB that is controlled by hardware in the following situations:

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.

For example, suppose an instruction is not accepted and VA page 30 is generated. For the following use cases, a TLB controlled by software might be preferable than one handled by hardware:

How many trap service routines could theoretically be created for the LC-3, given the format of the TRAP instruction? (hint: how many bits are used for the trap vector?) 8 64 O 256 О 16к 32

What happens to the Carry flag when the SHR AX,1 instruction is executed?

Let, in 8086 based system current SP value is FFFAh and the CS, IP and FL values are 7000h, 1000h and 1001h, respectively. Now, if at that instance an interrupt occurs, then show the stack increase and decrease scenario along with changes in SP values and stack contents.

SPIM: 1.Create a program (SPIM) that can find the values of a function f(a,b) =a+b using stack and the jump and link instruction. (i.e. a=2, b=3)
