Question

Which of the following memory access can reduce the clock cycles?

(a) bus interfacing

(b) burst interfacing

(c) dma

(d) dram

The question was posed to me in homework.

The origin of the question is Burst Interfaces topic in portion Memory Systems of Embedded Systems

Answer 1

Right option is (b) burst interfacing

The explanation: The burst interfaces reduces the clock cycles. For fetching four words with a three clock memory, it will take 12 clock cycle but in the burst interface, it will only take five clocks to access the data.
