In a blog post, Calista Redmond, chief of RISC-V International, which coordinates work among companies on the technology, hit out at moves by US lawmakers to pressure the Biden administration to impose export control restrictions around RISC-V.
Major US firms such as Qualcomm and Alphabet's Google have embraced RISC-V, but so too have Chinese firms such as Huawei, which the U.S. lawmakers argue constitutes a national security concern.
Redmond said RISC-V is no different than other open technology standards like Ethernet, which helps computers on the internet talk with each other.
"Contemplated actions by governments for an unprecedented restriction in open standards will have the consequence of diminished access to the global marketplace of products, solutions, and talent," Redmond wrote.
"Bifurcating on the standards level would lead to a world of incompatible solutions that duplicate effort and close off markets."
