computer science - CISC and RISC architectures -


i read lot difference between cisc , risc architectures different sources. 1 of things seemed agreed upon cisc used von neumann whereas risc used harvard architecture. couldn't quite grasp reason behind classification.

there no relations between instruction set (risc , cisc) architecture of processor (harvard architecture , von neumann architecture). both instruction set can used of architecture.

older arm architecture used von neumann architecture risc, , later arm9 shifted harvard architecture risc. latest arm processor uses more advanced hybrid architecture.
