RISC V - REFERENCE MODEL

Key Features of the RISC-V ISA

  • Delivers a new level of software and hardware freedom on architecture in an open extensible way.
  • Open ISA delivers easier support from a broad range of operating systems, software vendors and tool developers.
  • The open source of hardware, RISC-V does not rely on a single supplier – offers multiple suppliers, therefore, supports unlimited potential for future growth.
  • No other ISA is architected like the RISC-V ISA, allowing for user extensibility of the architecture without breaking existing extensions or incurring software fragmentation.

Advantages of RISC

  • RISC architecture is used in high-end applications such as video processing, telecommunications and image processing.
  • Used in MICROPROCESSORS and MICROCONTROLLERS.
