The correct answer is: Josh Fisher.
Josh Fisher is an American computer scientist who is best known for his work on the VLIW architecture. He is a professor of computer science at the University of California, Berkeley, and a co-founder of the company SiCortex, which developed the first commercial VLIW processor.
A VLIW (Very Long Instruction Word) architecture is a type of processor architecture in which multiple instructions are executed in parallel. This is done by having a single instruction word that contains multiple instructions, which are then executed by multiple functional units in the processor.
VLIW architectures are often used in high-performance computing applications, where they can achieve high performance by executing multiple instructions in parallel. However, they can also be more difficult to program than traditional architectures, as the programmer must ensure that the instructions in the instruction word can all be executed in parallel.
John Ellis, John Ruttenberg, and John O’Donnell are all computer scientists who have made significant contributions to the field of computer architecture. However, they are not the inventors of the VLIW architecture.
