This processor, which is fabricated on [[TSMC]]'s [[55nm process|55LP process]], is based on the {{ethz|PULP}} open core. The GAP8 incorporates [[9 cores|nine]] RISC-V cores along with a [[neural processor]] designed to accelerate [[convolutional neural network]]s (CNN). The GAP8 is said to offer a peak performance of up to 200 MOPS at 1 mW and up to 10 GOPS at a few tens of mW, making it well suitable for long autonomous battery-powered life. |

The microcontroller block is a fairly standard MCU with many of the standard features. The MCU is situated on its own power domain with the peripherals power switchable and configurable along with the clock generator. It consists of a single system management core (also called a fabric controller by GreenWaves) for tasks such as peripherals and it can double as general purpose low-power core, meaning compute engine can remain power-gated unless absolutely necessary. This core has its own 16 KiB of data cache and 4 KiB of instruction cache. | The microcontroller block is a fairly standard MCU with many of the standard features.

The MCU was designed to feel and behave like any other microcontroller on the market. It can be programmed using the familiar standard GCC/GDB toolchain derived from the one developed by the RISC-V foundation. Currently two real-time operating systems are supported, the PULP OS and Arm Mbed OS. GreenWaves has developed a full set of drivers for both of those operating systems in order to allow access to all the GAP8 peripherals. | The MCU was designed to feel and behave like any other microcontroller on the market.
