Meet the Powerful IA-840f:
Enterprise-Class Intel Agilex Based FPGA Accelerator
> Flexible, Customizable Hardware
> oneAPI Software Support

Tap Into the Power of Agilex

The new Intel Agilex FPGAs are more powerful, draw less power and add I/O features like PCIe Gen4.

  • 2nd-Generation HyperFlex Architecture: Up to 40 percent higher performance or up to 40 percent lower total power compared with Stratix 10 FPGAs.
  • DSP Innovation: Supports hardened BFLOAT16 and up to 40 teraflops of digital signal processor (DSP) performance (FP16).
  • Advanced memory support: Up to 128GBytes of DDR4 SDRAM memory.

DSP Innovation

The IA-840f FPGA features a configurable DSP engine with hardened support for single-precision FP32, half-precision FP16, BFLOAT16, and INT8 calculations. Agilex also supports low-precision configurations from INT7 to INT2 for maximum flexibility—ideal for evolving AI workloads.

2nd Gen Intel® Hyperflex™ Architecture

Continuous improvements to Intel Hyperflex deliver improved performance compared to Stratix 10 device designs. The 2nd Gen architecture thus greatly improve the productivity of customers and reduce time-to-market.

Hardened Protocol Support

The Agilex FPGA delivers optimal power, performance and logic utilization efficiency by integrating hardened protocols for many popular functions including 100G Ethernet and PCIe Gen 4.

Generation 4.0

Double the Bandwidth!

Built with the latest PCIe Gen4 interface, the IA-840F can transfer up to twice the bandwidth of Gen3 devices.

Enterprise-class for Deployment

Ramp to product with the power of Molex

The IA-840f is built on BittWare’s enterprise-class foundation stones: existing products and processes that are already proven through extensive validation. When it’s time to ramp to production, this means a faster turnaround and utilizing the same hardware you have been using for development.

Flexible Expansion IO

With QSFP-DDs and MCIO connectors, the IA-840f offers a range of flexibility to meet your application needs:

  • Three QSFP-DDs provide up to 600Gbps with hard IP for 10/25/100GbE links (up to 4× 100GbE total).
  • MCIO expansion ports let you optimize the IA-840F for your application with PCIe expansion such as:
    • 4× Gen4 x4 root ports
    • 1× Gen4 x16 root port

Inquire about customized Molex connectors/cables as required for your application.

Supporting Intel's oneAPI

Develop faster + reuse code in this software-orientated tool flow

Supporting high-level software tool flows is critical to a growing customer base who want to take advantage of heterogenous architectures. The new oneAPI from Intel is designed around code re-use while providing similar performance to other high-level tools.

BittWare recently completed an updated 2D FFT white paper using oneAPI and found the performance matches our optimized OpenCL-based approach.
