1. Do the following problems: a. Represent the decimal numbers: 512 and-59 in (x) sign-magnitude, (xox) 1's complement, (boox) 2's complement (64 bits). b. Represent the following numbers in decimal: 7CDF 4BEA FF30 A938H and DE78 14CB FE83 74CFH, if the original representation is interpreted as (x) unsigned, (xx) sign-magnitude, (oox) 1's complement, (xxxx) 2's complement c. Given the following (x86) declarations, draw the Big-Endian and Little-Endian layouts: varl WORD 1112H var) WORD 1314H varK WORD 1516H varL WORD 1718H warl DWORD 1112 1314H warJ DWORD 1516 1718H uarl QWORD 1112 1314 1516 1718H (BYTE: 8 bits, wORD: 16 bits, DWORD: 32 bits, QWORD: 64 bits) d. Use specific and concrete examples and diagrams to illustrate and explain each of the following addressing modes, (no definitions): Immediate, Direct, Indirect, Register, Register Indirect, Base-register, Displacement, Relative, Effective Address. hanchmark nraeram is run on a 2GHz processor.
