What is General Register Organization ? Design Common Bus system using Tri-State Buffer or Multiplexer. What are types of Addressing Modes? Explain with example. An instruction is stored at location 300 with its address field at location 301. The address field has value 400. A processor register R1 contains the number 200. Evaluate the effective address if addressing mode of the instruction is- (i) direct (ii) immediate (iii) relative (iv) register indirect (v) index register. A Bus-organized CPU has 16 registers with 32 bits each- (i) How many multiplexers are required. ? (ii) How many selection inputs are needed.? (iii) How many inputs & outputs are there in decoder? . A Memory size is 4096X16 words - what are sizes of different registers (AR, DR, PC, IR) ?. Also, discuss Memory transfer.
