SiFive Tapes Out First in a Series of 7nm IP Enablement Platforms

Includes critical IP validation for HBM2E 3.2Gbps Interface, TCAM and more

SAN MATEO, Calif.April 11, 2019 /PRNewswire/ — SiFive, the leading provider of commercial RISC-V processor IP and custom SoC solutions, today announced it has successfully taped out an IP enablement platform in 7nm FinFET technology that includes critical IP validation for SiFive’s high bandwidth memory (HBM2E) 3.2Gbps interface, 2GHz Ternary Content-Addressable Memory (TCAM) partner IP, a low-voltage differential signaling (LVDS) interface and other key IP building blocks. The high-speed IP interface enablement platform is the first in a series of SiFive’s next-generation platforms for high-performance and high-bandwidth applications. The forthcoming 7nm IP enablement platforms are:

  • HBM2E 2.5D ASIC SiP based on SiFive’s RISC-V Core IP with vector extension, TileLink – a high-performance, scalable, cache-coherent fabric; high-performance caches; HBM2E controller and PHY; support for low latency HBM memory; DMA and peripherals.
  • Customizable Freedom Revolution AI SoC platform based on SiFive’s 64-bit U7 and S7 Series RISC-V Multi-Core IP, TileLink, accelerator bays to connect a custom accelerator into the system, security IP, LPDDR5, an HBME controller and PHY, a PCIe5 SerDes and 56/112G SerDes.

“The design revolution taking place in the semiconductor industry has created unprecedented architectural freedom through customizable SoCs,” said Shafy Eltoukhy, senior vice president and general manager of the Custom SoC Business Unit at SiFive. “Our IP enablement platforms include internally developed IP along with the most robust, high-performance partner IP on the market for next-generation AI, networking and other high-performance applications in 7nm.”

Why Does It Take a Pandemic to Realize the Value of Remote Patient Monitoring?

Sponsored by Maxim Integrated

The headlines that COVID-19 are bringing to us each day serve to highlight the promise of remote patient monitoring. According to the U.S. Centers for Disease Control and Prevention, 6 in 10 American adults live with at least one chronic disease and 4 in 10 adults have two or more. The time is now to embrace and accelerate the deployment of remote patient monitoring to ensure that chronic conditions are managed in a way that can improve outcomes and reduce the need for regular healthcare facility visits.
