Need example about microprocessor logical instructions RCR & ROL
Homework Answers
| Opcode | operand | destination | example |
|---|---|---|---|
| RCR | D,C | rotates all bits in D to the right along with the carry flag C times | RCR BL,CL |
| ROL | R,C | rotate all bits in D to the left C times | ROL BX,06 |
RCR ( Rotate right through carry)
ROL (Rotate left without carry)

Write 8085 microprocessor instructions for the following
(ii) write the 8085 instructions to: 1. Load 90H in the accumulator. 2. Add 32H to the contents of accumulator. 3. Initialize stack pointer to FF00H. 4. Rotate accumulator left through carry 5. Store the contents of the accumulator into memory location E500H. 6. Transfer the program control to memory location D500H if carry flag is set. 7. Complement the content of the accumulator 8. Stop program execution

1. The MIPS instruction set includes several shift instructions. They include logical-shift-left (sll), logical-shift-right (srl), and arithmetic-shift-right (sra). [2 +2 4 points] a) Why does not MIPS offer an "arithmetic-shift-left (sla)" instruction? b) Write a MIPS code to implement the logical-shift-left (sll) instruction for a machine that did not have this particular instruction? In other words, you have to write the equivalent of the sll instruction using mul, add and other instructions. Try writing the equivalent of sll Ss1, Ss2,...

The instruction {mov AL, 57} is and example of using immediate addressing mode T/F? If AL = 35 h then after {not al, 1} it becomes AL = 6A h T/F? In assembly: the Immediate addressing mode is not allowed in the dec instruction T/F? Each running program (in the main memory) must have a code segment, T/F? Are these two assembly instructions (rol ax.3) and frel ax,3) exactly the same (YN)? Write a list four to six processors/microprocessors (Intel...

Consider a hypothetical microprocessor generating a 16-bit address (for example, assumethat the program counter and the address registers are 16 bits wide) and havinga 16-bit data bus.a. What is the maximum memory address space that the processor can access directlyif it is connected to a “16-bit memory”?b. What is the maximum memory address space that the processor can access directlyif it is connected to an “8-bit memory”?c. What architectural features will allow this microprocessor to access a separate“I/O space”?d. If...

use microprocessor 6812 instructions please
2. [Second program) Write a program that performs the same operations as the first program, except: a. Uses the stack to pass the parameters into the program b. Uses registers to return the value C. Use JSR for this program only d. For extra challenge, pass the return value using the stack (not mandatory)

Risk of loss (RoL) is one of those concepts that every business person knows about but doesn't want to acknowledge, something like knowing that you can be audited by the IRS but hoping that you will never be selected for an audit. With that caveat in mind, when goods are damaged or destroyed, which party bears the burden of the loss---buyer, seller, or warehouser (or carrier)? That is, in determining RoL, what factors do courts consider?
