Question

Which cache mapping have a sequential execution?

(a) direct mapping

(b) fully associative

(c) n way set associative

(d) burst fill

The question was asked by my college professor while I was bunking the class.

The above asked question is from Size of Cache topic in section Memory Systems of Embedded Systems

Answer 1

Correct answer is (d) burst fill

To explain I would say: The burst fill mode of cache mapping have a sequential nature of executing instructions and data access. The instruction fetches and execution accesses to sequential memory locations until it has a jump instruction or a branch instruction. This kind of cache mapping is seen in the MC68030 processor.
