At the annual RISC-V Summit this week, Samsung disclosed the use SiFive’s RISC-V cores for upcoming chips for a variety of applications. The company is joining a growing list of leading high-tech companies that have adopted the RISC-V architecture.

One of the applications that Samsung is using RISC-V cores in is mmWave RF processing by its upcoming 5G RF front-end modules. The latter will be used for Samsung’s flagship 5G smartphones due in 2020. The RISC-V cores will also be used for AI image sensors, security management, AI computing & control.

It is noteworthy that Samsung taped out its first chip with a RISC-V core(s) as early as in 2017, so it started to work on it even earlier. In three years, Samsung has iterated on its designs and is now planning to adopt RISC-V cores for commercial applications, starting from mmWave RF processing in mobiles and expanding beyond them.

Besides the announcement of the RISC-V core integration, it's also Samsung's first instance of them talking about their mmWave modules in public. Unlike Qualcomm, Samsung tends to remain quiet about their developments until it's nearing commercialisation, and even then in a lot of cases we don't know too much about their designs. Nevertheless, it looks like the company has had mmWave designs for some time.

Samsung will be the fourth major company that has publicly disclosed its plans to adopt the open-source RISC-V architecture after Western Digital, NVIDIA, and Qualcomm. Western Digital intends to use the technology for a variety of applications, including SSD and HDD controllers. NVIDIA reportedly plans to use it for GPU memory controllers, whereas Qualcomm is set to use RISC-V for mobile SoCs.
