Dmitry Grebennikov argues RISC-V has fundamental architectural contradictions — a single ISA cannot optimally serve both supercomputers and tiny microcontrollers simultaneously, as their design requirements are diametrically opposed. He predicts RISC-V will still dominate low-cost MCU space, but attributes this success to practical improvements over 8051 rather than its ISA design.
Background
Dmitry Grebennikov is a hardware security researcher known for critical analysis of CPU architectures. This article is part of his ongoing critique of RISC-V's design philosophy and practical limitations.
