Question

(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 2. A benchmark program is run on a 2GHz processor. The executed program consists of 1,000,000 instruction executions, with the following instruction mix and clock cycle count: Cycles per Instruction Instruction Type Integer arithmetic Data transfer Instruction Count 450,000 320,000 150,000 80,000 Floating point Control transfer 2 etermine: a. Effective CPI b. MIPS rate. c. FLOPS rate Page

Explanation / Answer

Solution:

2 a)

Let's calculate the effective CPI

We need to consider the amount of utilization every process is occupying to calculate the effective CPI

Effective CPI= (450000/1000000) * 1 + (320000/1000000) * 2 + (150000/1000000) * 2 + (80000/1000000) * 2

= 1.55

b)

MIPS rate=

The clock rate is 2 GHz

to execute 1 instruction it will take= 1/(2 * 10^9)= 0.5 ns

in MIPS= 1/0.5 * 10^-9= 2000 MIPS

c)

FLOPS rate= 2 * 10^9= 2 GFLOPS
