Hi
There are two types of processor architecture: Von Neumann Architecture and Harvard Architecture. Which of the two processor architectures is better and why?
Hi
In Von Neumann Architecture, there is only one single memory for storage of data and programs. In Harvard Architecture, there are two separate memories for data and program storage. The Harvard Architecture makes pipelining easier and carries out instructions in lesser time. Thus, Harvard Architecture is better.
Every computer operates on extremely low-level commands which perform several extremely basic functions like jumping to addresses, calculating basic mathematics, reading data, and writing data. The entire list of commands that a CPU can run is called instruction set. The instruction set is comparatively small.
Majority of the programming languages such as Fortran, C++, Visual Basic, or Ada have to be compiled first to these low-level commands to be able to run. The architecture of a processor chip is an explanation or a description of its basic operations and basic components. Every processor family or processor series has its own architecture.
The programming view of the architecture of a specific processor is called the assembly language and every type of processor has its own assembly language. When you study assembly language, you also learn the architecture of a specific processor. The learning of any assembly language raises your professional comprehension of computers.
There are two types of basic CPU architecture: CISC or Complex Instruction Set Computers and RISC or Reduced Instruction Set Computers. The most common and recognized microprocessor architecture is CISC. RISC is quite a newcomer. Intel’s Pentium and 80×86 microprocessor series are CISC-based though RISC-type functionality has already been integrated into Pentium CPUs.
