RISC-V Tornado configurable 32-bit processor SoC subsystem


The RISC-V Tornado platform is a configurable AMBA based SoC subsystem allowing our user to customize the platform depending on its application requirements. RV32 Tornado mixes standard peripherals and interfaces (GPIO, timers, watchdog, I2C, SPI) and more intelligent ones (interrupt controller, DMA controller, cache controller, FPU, DSP).
RISC-V Tornado is proposed with an advanced IDE enabling power-aware code development and fast Time To Market. SmartVision? IDE fully supports GCC RISC-V compilation toolchain, is available under Windows and Linux and embeds advanced debug functionalities: TLM and cycle accurate simulator, breakpoint on complex sequences of events, hardware debugging with BIRD?, speed and power profiling.
RV32 Tornado is delivered with software low level drivers, low footprint SmartLib C standard library and FreeRTOS for RISC-V.

Robustness is ensured

For more than 15 years, Dolphin Integration has built a testsuite for checking the functionality of any configuration of the RV32 Tornado at any representation level (RTL down to silicon).The testbenches have evolved a lot thanks to users feedback.
The testbench is delivered with its documentation to our microcontroller core users so that they can apply it on their own project and ensure functionality.
