Question

4. What are the important factors that influence the performance of a microprocessor? How do you determine the maximum size of physical memory that can be addressed by the processor? 5. How did the performance of the processors improved during the past 35 years-What are the design approaches implemented to improve the performance? What are the differences between a SRAM and DRAM? What is bidirectional data line? How are the memory cells accessed within the memory device? Indicate the arrangement of decoders in 6. 7. detail. Give a sketch. (Rows, columns)

Explanation / Answer

4. Important factors influencing the performance are:

a) RAM size

b) The absolute size of the register it is using

c) Clock cycle and generation of the CPU.

d) The cache memory of the CPU.

It can be calculated using the principle that If a machine word is N bits and an addressed is stored in a register, then the address is 2^ N different locations.

5.It is improved drastically by because of the evolution of VLSI and microprocessors.

Which provides the thread control and -program control.

Moore Laws also plays a vital role in this.

6.

SRAM stands for static random access memory.

It uses flip-flopsto store each bit. These flip flops on a complex level of SRAM is called  bistable latching circuitry.

DRAM stands for dynamic random access memory.

It basically store every data in small separate capacitors which in turn linked with the integrated circuit.

Billateral data line is basically aline wof flow of data which use both types of RAM i.e SRAM and DRAM.

7. Memory address is accessed by programing the chips pin address.

Decoder is basically opposite of Encoder and its function is to decode the the signal into primary bits.
