Seagate develops RISC-V based processors for faster and secure HDDs

Must Read

Storage solution giant Seagate Technology has announced that they have designed two processors based on the open RISC-V instruction set architecture (ISA). One is designed for high performance while the other features a design specialized for area optimization.

The former enhances real-time processing performance in HDDs by introducing advanced servo algorithms. While the latter features a flexible microarchitecture configuration and feature set, optimized for footprint and reduced power consumption.

This has been tried to work with HDDs, and at the initial stage, it is said that it was possible to achieve up to 3 times the performance of the current one. Seagate made this announcement at the virtual RISC-V Summit 2020.

Cecil Macgregor, Vice President, Application-Specific Integrated Circuit (ASIC) Development said, “Having shipped close to one billion cores over the last year, Seagate has developed significant expertise in system-on-a-chip design. 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 the implementation of advanced servo 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 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, the company is committed to open and transparent security.

As both of the processors offer RISC-V security features, the benefits add up to more robust edge-to-cloud data trustworthiness, security, and mobility, making newer HDDs faster and secure.
