RISC-V was born from the dire need to address the skyrocketing cost of designing and manufacturing increasingly complex new chip architectures, as a result of the economic demise of Moore's Law. SiFive's hardware designs leverage the body of software and tools available from the open-source community under the guidance of the RISC-V Foundation, dramatically reducing the cost of developing custom silicon. System designers can use the SiFive Freedom platforms to focus on their own differentiated processor without having the overhead of developing a modern SoC, fabric or software infrastructure.
"RISC-V represents a bold new path for system designers in embedded and industrial markets," said Ted Speers, head of product architecture and planning for Microsemi Corporation's SoC business unit. "We went to SiFive not only because its co-founders created RISC-V, but also due to its team's agile methodology, which enabled the company to deliver a complete RISC-V sub-system and tool-chain targeting our secure, low power SmartFusion™2 SoC FPGA platform on a very aggressive schedule."
The Freedom platforms comprise a complete software specification, board OS support packages (BSPs), development boards and base silicon. The platforms provide customers the ability to create their own silicon enhancements and customizations, which SiFive then quickly incorporates and delivers to the customer at a much lower cost and faster time-to-market than traditional custom silicon designs. The platforms also provide significant performance and power advantages over existing microcontrollers and FPGAs.
- Freedom U500 Series: The Freedom Unleashed (U) family features a fully Linux-capable embedded application processor featuring the world's most advanced, multicore RISC-V CPUs, running at a speed of 1.6 GHz or higher with support for accelerators and cache coherency. Designed in TSMC 28nm, the Freedom U500 platform targets initial customers in diverse markets such as machine learning, storage and networking. The Freedom U500 platform also supports standard high-speed peripherals including PCIe 3.0, USB 3.0, Gigabit Ethernet, and DDR3/DDR4.
- Freedom E300 Series: The Freedom Everywhere (E) family is designed for embedded microcontroller, IoT and wearables markets. Designed in TSMC 180nm and architected to have minimal area and power, the Freedom E300 platform features the world's most efficient RISC-V cores with support for RISC-V compressed instructions, which have been shown to reduce code size by up to 30 percent.
To give developers a head start on software development, full FPGA models of each SoC are available through SiFive today. Developers will also be able to prototype their customizations in the form of custom RISC-V instructions, accelerators and co-processors.

SiFive will showcase the Freedom family of SoC platforms during the RISC-V 4th Workshop in Boston on Tuesday, July 12.
SiFive is the first fabless semiconductor company to build customized silicon based on the free and open RISC-V instruction set architecture. Founded by RISC-V inventors Krste Asanovic, Yunsup Lee and Andrew Waterman, SiFive democratizes access to custom silicon by helping system designers reduce time-to-market and realize cost savings with customized RISC-V based semiconductors. SiFive is located in San Francisco and has venture backing from Sutter Hill Ventures. For more information visit www.sifive.com.
