Open-V

Here at Onchip, we are developing a 32-bit microcontroller featuring a new architecture RISC-V, created by The Computer Research Group at Berkeley. This is the first microcontroller on this architecture in the world, and the first microcontroller ever in Colombia. All communications between masters and slaves are done using AXI4-Lite, a free-to-use protocol designed by ARM Holdings and typically used for interconnect bus modules for the ARM architecture. The bus is intended for adapting different applications for any microcontroller that industries want to build. The microcontroller has different peripheral. First, a SPI master allows to program and debug the operation and also an SPI slave was added to capture information. Second, the microcontroller has 8 GPIOs with a current capability up to 20mA. Finally, the analog-digital interfaces helps to verify all functionalities. The chip has a SAR ADC operating up to 10 MHz and a R2R DAC to manage audio outputs. RISC-V is intended to be a new open-source and open-hardware standard for mobile processors. A lot of people are involved, including big companies such as Google, Intel, Nvidia, HP, IBM, Microsoft, etc. Also, very important universities such as Berkeley, Cambridge, and ETH Zurich are working processors based on RISC-V. RISC is always characteristic for occupying very low resources with a very high instruction-performance, reducing the Instruction Set and making programs a bit harder to program but with a lot of performance benefits.
