Such systems are easier to build, and provide the performance advantages of a Harvard architecture ... The microarchitecture in a system will define the storage element/data paths and how they will be implemented into the instruction set architecture, the microarchitecture also is responsible for data processing. The Harvard architecture has separate memory space for instructions and data which physically separates signals and storage code and data memory, which in turn makes it possible to access each of the memory system simultaneously. In this case, there are at least two memory address spaces to work with, so there is a memory register for machine instructions and another memory register for data. The Harvard architecture, with its strict separation of code and data processes, can be contrasted with a modified Harvard architecture, which may combine some features of code and data systems while preserving separation in others. The Harvard architecture characterized by the Harvard Mark 1 used physically separate memory and data paths for program and memory. It has an advantage over the von Neumann architecture, if the CPU supports pipelining, i.e. This article intends to explore the concept of modularity, namely its advantages in the application to architecture projects.
