RISC-V International has more than 1,000 members across over 50 countries who are working in hardware, software, services, and various industries for a strong and healthy RISC-V ecosystem. It is projected that by 2025 there will be over 62 billion RISC-V CPU cores and the total market for RISC-V IP and software is expected to grow to over $1b by 2025.   In 2020 alone, we saw successes with newly defined RISC-V accelerator architectures, affordable RISC-V open source small-board computers, development boards for personal computers, and an incredibly fast 64-bit RISC-V Core as the community also ratified key specifications and made advances in security.  As we see the growth of RISC-V into industries such as AI, machine learning, blockchain, 5G, medical, and industrial, we will see the ratifications of new extensions that enable this growth. Join Kim McMahon, Director of Marketing and Stephano Cetola, Technical Program Manager as we take a look at where RISC-V is going in 2021.

2. Welcome to the RISC-V presentation! Meet:
Kim McMahon
Director of Marketing
Kim has a deep background in
open source and technology.
She has spent her career with
companies such as SGI, Cray,
VMware, and the {code} Team at
Dell, where she honed her love
for HPC, open source, and cloud
native.
A long-time Colorado girl, she lives in Winter Park, Colorado and
enjoys hiking, skiing, and outdoor activities with her two labradors
Coal and Connor.
Stephano Cetola
Program Manager
Stephano is a technical program
manager for RISC-V
International. He has worked on
and managed numerous open
source initiatives in software and
hardware.
Before joining the RISC-V team, Stephano was employed at
Intel contributing to the Yocto Project building embedded
Linux distros and working on TianoCore, an open source
implementation of UEFI. He is involved in research at Portland
State University focusing on Trusted Execution Environments
and hardware security testing.
