1.	What is the main idea of the writing scheme in the cache memory?(a) debugging(b) accessing data(c) bus snooping(d) write-allocateThe question was posed to me during an online interview.I'm obligated to ask this question of Writing Scheme of Cache Memory topic in section Memory Systems of Embedded Systems
Answer» The correct CHOICE is (c) bus snooping Explanation: There are four main writing scheme in the cache MEMORY which is, write-through, write-back, no CACHING of the write cycle and write BUFFER. All these writing schemes are designed for bus snooping which can reduce the coherency.
