(2) (a) In class, we examined an algorithm to generate the 2'sC of an integer (flip all bits; add 1). We also saw how any ber in binary can be directly represented in hex. Work out an algorithm that takes a number in hex and directly obtains its 2'sC representation i hex (e.g. OrBEEF-0r4111). Justify your answer i.e. give reason(s) why your algorithm works co rectly (b) The following bit patter, OrCOD was found in a 12-bit register. What is the decimal number represented if it is interpreted as: (i) unsigned binary; (ii) sign-magnitude; (iii) Two's complement? (c) The first two bytes of a 1M x 16 main memory have the following values: byte at address 0 is OrFF and byte at addressl is 0r01. If these bytes hold a 16 bit 2's complement integer, what is the actual decimal value stored in the word (read as a unit) if the memory is (i) big endian (ii) little endian
