Assume that a mad scientist has created a computer that has 12-bit registers(storage). The most significant bit is the sign bit. He wants to execute the followingcomputation using 12-bit register.124-435 (Subtract decimal 435 from decimal 124)Use 2's complement method (in binary) to find the result of the above operation inbinary system.

Write a program (Rotate.asm) in HACK assembly that implements an algorithm to rotate the bits of a 16-bit number left (Least Significant bit (LSb) to Most Significant bit (MSb)). The original number should be stored in RAM[3] the number of times to rotate the bits should be in RAM[4] and the result stored in RAM[5], i.e. 10101111 rotated left 3 times would be 01111101 where the MSb is used to replace the LSb.

In MIPS assembly, implement integer division using rounding (rather than truncation). This is accomplished by taking the remainder of the division and dividing it by the original divisor. If the new quotient is higher than or equal to one, multiply it by one.Otherwise, leave the original quotient alone.In MIPS assembly, implement integer division using rounding (rather than truncation).
