Freedom E310 & Low-Cost Hifive1 Development

Freedom E310 & Low-Cost HiFive1 Development Board

Jack Kang VP Product & Business Development [email protected] 11/29/2016 Introduction to SiFive

• Founded by RISC-V Inventors Krste, Andrew, and Yunsup

• Fabless semiconductor company building customizable SoCs

• Open SoC Platforms to encourage software/ecosystem development

• Explained our business model:

Fabs 3rd Party IP Specs and/or IP EDA Tools Packaging & Test Customer Chip Design Factory Logistics Custom RISC-V SoCs

SiFive is fast time-to-market, low-cost, low-risk, customizable

• Introduced our product lines:

CPU Core IP SiFive Freedom SoCs

Soft IP Cores: Low cost, 32-bit microcontrollers High performance, 64-bit multi- • No-royalties highly-customizable for: core SoCs customized for: • Customizable • IOT • Datacenter Accelerators • Embedded • Storage / SSD Controllers • Wearables • Networking / Baseband

• We asked you to develop on our FPGA platform, and to download bitstreams from dev.sifive.com

• We promised that RISC-V silicon was coming “soon”…

• That was 4 months ago

• Introducing the Freedom E310

• First member of the Freedom Everywhere family of customizable SoCs
