SiFive Essential

The SiFive Essential™ family is a portfolio of processor cores that spans from high-performance multi-core heterogeneous application processors to area-optimized, low-power embedded microcontrollers. SiFive Essential standard core microarchitectures are based on the RISC-V ISA to provide 64-bit and 32-bit options.

You can tune SiFive Essential cores to your workload using SiFive Core Designer, leveraging the flexible generator style SiFive uses to design processor architectures for different classes of performance and efficiency. SiFive Essential Standard cores based on our flexible microarchitecture designs are pre-configured for common use cases and are the perfect starting point for designing your own core in SiFive Core Designer.

Get started with a free Standard Core evaluation, or build your own custom core design, and receive Verilog RTL and FPGA bitstream.
