RISC-V Summit 2022

RISC-V is going places. From cars to space to data centers. But what about the billions of cores in more mundane applications such as greeting cards, toys or keyboards? This is an area traditionally served by 8-bit CPUs, but not for much longer. The award-winning SERV, the world's smallest RISC-V CPU is small enough to take on the 8-bit market while offering all the convenience of the modern RISC-V ecosystem, such as running the Zephyr RTOS. This presentation takes a look at what makes SERV so small, what it can do, how and where it is used today along with a proposed new ISA extension to further improve the applicability of RISC-V within deeply embedded systems.
