Homework Answers
-
Arithmetic operations have a potential to run into a condition known as overflow.
-
Overflow occurs with respect to the size of the data type that must accommodate the result.
-
Overflow indicates that the result was too large or too small to fit in the original data type.
-
When two signed 2's complement numbers are added, overflow is detected if:
-
both operands are positive and the result is negative, or
-
both operands are negative and the result is positive.
-
-
When two unsigned numbers are subtracted, underflow occurrs if
-
there is a borrow out of the leftmost bit.

1. Compute the decimal value for the following bit pattern, assuming it is a single-precision floating point number (show major steps): 1100 0011 0001 0010 0100 1001 0010 0100 2. Convert the decimal -2118.75 into single-precision floating point number (show major steps). 3. Assume -75 and -122 are signed decimal integers stored in 8-bit sign-magnitude binary format. Calculate -75 + -122. Is there overflow, underflow, or neither?

Problem 1: Write a function add64 that adds two input unsigned 64 bit integers x and y and returns the unsigned 64 bit integer sum z, i.e. zx+y. In your main function, you should assume that x, y, and z will be stored in the following 6 registers as follows: x: upper 32 bits in $t1 y: upper 32 bits in St3 z: upper 32 bits in St5 lower 32 bits in $to lower 32 bits in $t2 lower 32...

Assume that 151 and 214 are signed 8-bit decimal integers stored in two’s complement format. Calculate 151 + 214 by adding the two’s complement numbers first and then writing the final result in decimal. Then explain why the final result is very different from 366 (151+214=366). Note that if a number requires more than 8 bits, you need to represent first the number correctly using as many bits as necessary, then keep only the 8 bits, and use the resulting...
