The growing free-CPU RISC-V ticks off another niche at Embedded World 2019 where will be used for motor control. Later this year, Trinamic will release the engine control circuit Rocinante in three versions.
The company claims to have chosen a 32-bit RISC-V instead of Arm because it is open source. This means that there is nothing that limits the possibilities of developing it further. It also means that you are not in the lap of a supplier who may be bought. For example, the RISC-V core can be used to make the motor controller smart – it can run algorithms for predictive maintenance. Or it can run a user interface or manage a bus protocol like Can or USB.
