Seagate Technology plc (NASDAQ: STX) announced that it has
designed two processors based on the open RISC-V instruction set
architecture (ISA).
One of the open standards-enabled cores is designed for high
performance and the other is area-optimized. The high-performance
processor has already been built with RISC-V-enabled silicon and
demonstrated as functional in hard disk drives (HDDs). The
area-optimized core has been designed and is in the process of
being built.
Because both processors offer RISC-V security features, the
benefits add up to more robust edge-to-cloud data trustworthiness,
security, and mobility—all essential in the era when so much data
is on the move.
The announcement, made today at the virtual RISC-V Summit 2020,
is the first public report on the results of Seagate’s several
years of collaboration with RISC-V International.
“Having shipped close to one billion cores over the last year,
Seagate has developed significant expertise in system-on-a-chip
design,” said Cecil Macgregor, Vice President, Application-Specific
Integrated Circuit (ASIC) Development. “We now expanded the
capability to add customized RISC-V cores to our portfolio, which
is critical to future products. We live in a time of unprecedented
growth of enterprise data—and much of this data is in motion. These
cores will allow devices to share a common RISC-V ISA. Using open
security architectures, they will enable more secure movement of
data.”
The high-performance core offers up to triple the
performance for real-time, critical HDD workloads versus current
solutions. In an initial use case, this core enabled Seagate to
dramatically increase the real-time processing power available. The
processor paves the way for finer positioning by implementation of
advanced servo (motion control) algorithms.
The area-optimized core boasts a highly configurable
microarchitecture and feature set. It’s optimized both for
footprint and power savings. It powers auxiliary, supporting, or
background workloads. It can execute security-sensitive edge
computational operations (including next-generation post-quantum
cryptography) while targeting a small-footprint implementation of
security features over performance.
One of the key use cases for this core is security. A member of
OpenTitan, Seagate is committed to open and transparent
security.
“We see a significant potential for open, extensible
architectures like RISC-V,” said Dominic Rizzo, OpenTitan Project
Director and Engineering Lead at Google Cloud. “OpenTitan’s
open-source implementation benefits from RISC-V’s open nature,
enabling pan-industry transparency, trust,, and silicon security. Because Seagate
understands the promise of RISC-V for security, we are excited to
collaborate with Seagate on the open-source silicon root of trust
we are currently developing.”
The Seagate cores will also accelerate real-time analysis in the
data center and at the edge. Such analysis is crucial to the work
of scientific communities with mass data needs.
“At Los Alamos National Laboratory, using computational storage
to move processing near data has begun to significantly alter the
way we analyze data and perform scientific discovery,” said Brad
Settlemyer, Sr. Research Scientist at Los Alamos National
Laboratory. “By having compute integrated closely with storage we
are able to create persistent data transformations that speed up
data analysis by 1000-fold. This greatly relieves our primary
compute tier from these tasks. We will be continuing our drive
toward efficiency gains for our mission needs by partnering with
vendors and actively participating in important industry
initiatives like computational storage.”
Seagate has determined that solutions on this front tend to
involve custom silicon: that's where RISC-V shines.
“Introducing RISC-V to storage devices creates an opportunity to
implement application-specific computational capabilities that
enable massive parallel computational storage solutions,” said John
Morris, Seagate's Chief Technology Officer. “We believe that these
architectures support many important use cases that include
scientific simulation (for example, weather prediction) as well as
the learning part of machine learning.”
