As RISC-V chips are coming onto the market, chipmakers seem interested in not paying licensing fees with new hard drives shipping with RISC-V cores. The latest development in open instruction sets chips comes from OpenISA. They’ve developed the VEGAboard, a dev board with two RISC-V chips and Arduino-style pin headers.
The VEGAboard comes loaded with an NXP chip which combines an ARM Cortex-M0 and Cortex-M4. The real trick is the RI5CY and Zero-RI5CY chips on the VEGAboard, a four-stage RISC-V RV32IMCCXpulp CPU, which come from a PULP platform with a parallel platform for various processing needs. In short, with the VEGAboard, you’re not running a blink() sketch on the RISC-V microcontroller but on the ARM microcontrollers, while using the RISC-V chip to read accelerometers and toggle pins. It’s a coprocessor, but it’s RISC-V.
