What are the direct and indirect addressing capacities of processors with the address widths (a) 4, (b) 8 and (c) 16?


The direct addressing capacity of a processor is found by calculating 2A where A is the address width. Indirect addressing capacity is found by calculating 22A Therefore,

Direct addressing capacity                      Indirect addressing capacity

(a) 2A = 16                                              (a)   2(2*4)  = 256 bytes

(b) 28 = 256                                            (b)  2(2*8) = 65536 bytes

(c) 216 = 65536                                       (c)   2(2*16) = 4294967295 bytes
