Who coined the term RISC?

The correct answer is: A. David Patterson.

David Patterson is a computer architect and professor emeritus at the University of California, Berkeley. He is best known for his work on reduced instruction set computing (RISC) architecture, which has had a major impact on the design of microprocessors.

Patterson coined the term RISC in 1980, while he was working on the Berkeley RISC project. The goal of the project was to design a microprocessor that was simpler and faster than existing microprocessors. RISC microprocessors are characterized by a small number of simple instructions, which are executed quickly and efficiently.

Patterson's work on RISC architecture has had a major impact on the design of microprocessors. Today, most microprocessors are based on RISC principles. RISC architecture has also been used in the design of other types of processors, such as graphics processing units (GPUs).

Von Neumann, Michael J Flynn, and Harvard are all computer scientists who have made significant contributions to the field of computer architecture. However, none of them coined the term RISC.
