Samsung ports Tizen OS to RISC-V
Samsung has ported its Tizen OS operating system to a RISC-V core from SiFive for use in smart TVs.
The port of Linux-based Tizen OS runs on the 64bit SiFive Performance P470 core which has a 128-bit RISC-V Vector ALU to provide over 8 SpecINT2k6/GHz and still within similar area and power budgets of other chips using an ARM A55 core.
“Our partners at Samsung Visual Display discussed the work they have been doing to port the Tizen operating system to RISC-V. Tizen is an open-source operating system that is used in many Samsung smart T.V.s and it makes sense that they would look to the fast growing, global open-standard RISC-V to develop future systems. They also demonstrated a T.V. running on RISC-V and using a SiFive Performance P470 based core,” said John Ronco, senior vice president of product at SFive.
“Our global hardware and software teams have worked closely with Samsung teams to understand the challenges and today’s announcement is the culmination of a lot of great work by teams at both companies,” he said.
The P470 64-bit RISC-V core has a three issue, out-of-order pipeline tuned for scalable, highly efficient performance with private L2 caches and streaming prefetcher for improved memory performance, saving costs in a consumer smart TV>
It also has an interrupt controller with support for MSI style interrupts and virtualizationn with system Level Virtualization IP and cache stashing to L3 for tightly coupled accelerators. All of these point to the use of AI accelerators in future Samsung smart TVs.
