Question

1. For IEEE 754 single precision floating point, write the hexadecimal representation for -1.0.

2.For IEEE 754 single precision floating point, what is the number, as written in binary scientific notation, whose hexadecimal representation is:
0061 0000

3.Assuming nine-bit two's complement binary representation, convert 1B4 from hexadecimal to decimal. Remember to check the sign bit:

1B4 (hex) = _____ (bin) = ______ (dec)

4.Suppose you need to process a list of 31,000 integers contained in Pep/8 memory at one integer per word. You estimate that 20% of the instructions in a typical program are unary instructions. Keep in mind that your applications program must share memory with the operating system and your data.

Your program can have a maximum of:____
unary instructions and______
nonunary instruction

Explanation / Answer

1. For IEEE 754 single precision floating point, write the hexadecimal representation for -1.0.

1 11111111 0000000000000000000000

2.For IEEE 754 single precision floating point, what is the number, as written in binary scientific notation, whose hexadecimal representation is:
0061 0000

0 0000 0000 0110 0001 0000 0000 0000 0000

3.Assuming nine-bit two's complement binary representation, convert 1B4 from hexadecimal to decimal. Remember to check the sign bit:

1B4 (hex) =0001 1011 0100 (bin) = 436 (dec)

4.Suppose you need to process a list of 31,000 integers contained in Pep/8 memory at one integer per word. You estimate that 20% of the instructions in a typical program are unary instructions. Keep in mind that your applications program must share memory with the operating system and your data.

Your program can have a maximum of max of 3875 Byte

unary instructions and 775 Byte
nonunary instruction 3100 Byte
