Cache Memory Writing Scheme MCQ Quiz – Objective Question with Answer for Writing Scheme of Cache Memory

21. In which of the following access, the address is supplied?

A. the first access
B. the second access
C. third access
D. fourth access

Answer: A

In the burst interface, the address is supplied only for the first access and not for the remaining accesses. External logic is required for the additional addresses for the memory interface.

 

22. What type of timing is required for the burst interfaces?

A. synchronous
B. equal
C. unequal
D. symmetrical

Answer: C

The burst interfacing uses unequal timing. It takes two clocks for the first access and only one for the remaining accesses which makes it unequal timing.

 

23. How can gate delays be reduced?
A. synchronous memory
B. asynchronous memory
C. pseudo asynchronous memory
D. symmetrical memory

Answer: A

The burst interfaced is associated with the SRAM and for the efficiency of the SRAM, it uses a synchronous memory on-chip latches to reduce the gate delays.

 

24. In which memory do the burst interfaces act as a part of the cache?

A. DRAM
B. ROM
C. SRAM
D. Flash memory

Answer: C

The burst interface is associated with the static RAM.

 

25. Which of the following uses a wrap-around burst interfacing?

A. MC68030
B. MC68040
C. HyperBus
D. US 5729504 A

Answer: B

MC68040 is developed by Motorola and uses wrap-around burst interfacing. MC68030 is also developed by Motorola but it uses a linear line fill burst. HyperBus can switch to both linear and wrap-around bursts. US 5729504 A uses a linear burst fill.

 

26. Which of the following is a Motorola protocol product?

A. MCM62940
B. Avalon
C. Slave interfaces
D. AXI slave interfaces

Answer: A

MCM62940 protocol is developed by Motorola, whereas Slave interfaces, and AXI slave interfaces are for ARM. Avalon is developed by Altera.

 

27. Which of the following uses a linear line fill interfacing?

A. MC68040
B. MC68030
C. US 74707 B2
D. Hyper Bus

Answer: B

MC68030 uses a linear burst fill whereas MC68040, US 74707 B2 uses wrap-around burst interfacing. HyperBus can switch to both linear and wrap-around interfacing.

 

28. Which of the following protocol matches the Intel 80486?

A. MCM62940
B. MCM62486
C. US 74707 B2
D. Hyper Bus

Answer: B

The MCM62486 has an on-chip counter that matches the Intel 80486 and is developed by Motorola.

 

29. Which of the following protocol matches the MC68040?

A. MCM62486
B. US 5729504 A
C. HyperBus
D. MCM62940

Answer: D

The MCM62940 and MCM62486 are the specific protocols developed by Motorola, in which the MCM62940 has an on-chip counter which matches the wrap-around burst interfacing of the MC68040.

 

30. The modified bit is also known as

A. dead bit
B. neat bit
C. dirty bit
D. invalid bit

Answer:c

The dirty bit is said to be set if the processor modifies its memory. This bit indicates that the associative set of blocks regarding the memory is modified and has not yet been saved to the storage.
