Significant logic capacity, power-efficient performance, and advanced I/O capabilities

Lattice’s Avant™ platform expands into the mid-range FPGA market, building on its low-power legacy. Jungo WinDriver complements this by enabling fast, portable, user-mode PCIe driver development without kernel coding.


Launched as part of Lattice’s expansion into high-capacity, low-power FPGAs, the Avant family includes:

  • Avant-G: Designed for general-purpose mid-range applications. Offers up to 637K system logic cells, DDR4/LPDDR4 memory support, and up to 28 SERDES channels at 12.5 Gbps.

  • Avant-X: Tailored for high-throughput, high-bandwidth applications. Supports DDR5, more robust SERDES (up to 25 Gbps), and advanced security features.

These FPGAs are built on a 16nm FinFET process, balancing performance with energy efficiency. Both support industry-standard interfaces, including PCI Express Gen4, which is crucial for high-bandwidth, host-to-device communication.


Built-In Support

DMA Support with Lattice FPGAs and WinDriver

DMA (Direct Memory Access) is critical in FPGA applications where large data transfers must bypass the CPU. Lattice’s Avant FPGAs integrate PCIe blocks and memory-mapped register spaces suited for DMA engines.

​​

WinDriver DMA Features:

  • Sample drivers for DMA read/write, buffer locking, and interrupt handling.

  • APIs such as WDC_DMAContigBufLock(), WDC_DMASyncIoctl(), and WDC_IntEnable() to support bidirectional data flow.

  • User-mode access to BAR memory and DMA descriptor management.

While Lattice doesn’t yet provide official DMA samples specific to Avant-G/X with WinDriver, they do provide working DMA integration for their CertusPro-NX platform—another PCIe-capable FPGA series. These samples demonstrate DMA transactions via a PCIe endpoint and can be adapted to Avant-based systems due to architectural similarity in their PCIe interface.

​​

Platform Compatibility and Toolchain Synergy

Lattice’s development tools integrate well with system-level workflows:

  • Radiant® Software: For logic design, IP integration, synthesis, and simulation. Supports Avant-G/X.

  • Propel™ Builder: For creating and integrating soft processors and system IP.

  • PCIe IP Cores: Available for configuring custom endpoints with DMA logic.

When building a PCIe application on Avant FPGAs, Radiant can be used to assign BARs, implement AXI-based register maps, and instantiate custom DMA logic. WinDriver can then be configured to map these registers and manage host-side data transfer in minutes.

This allows a developer to go from FPGA image to working host communication using only Radiant and WinDriver—cutting development cycles and debugging overhead.

Testimonials

Inomed- Jörg Wipfler (Head of R&D)
“Usually, if a problem occurs during the development process, you don’t know whether it’s in the firmware – or even in the hardware – or in the software on the PC, WinDriver helped enormously to avoid such problems.”
GE Healthcare - Yann Casteignau (Principal Engineer Digital Hardware Design)
“We were looking for a driver to allow access to the board’s resources for a Windows 2000-based software. Having no intention to develop the driver in-house, we then searched the web and found Jungo’s solution.”
Brookhaven National Laboratory - John Haggerty (Data Acquisition Coordinator)
“I have been impressed with the relative ease with which one can develop a high performance driver for a PCI card without much detailed knowledge of the computer’s hardware or even the system software."
BittWare - Dave Hedstrom (Senior Software Engineer)
“When we tried Jungo’s WinDriver, we were immediately pleased with what they had to offer, using only the evaluation version, we found that none of the limitations of the competing tool that we were faced with, applied to Jungo’s WinDriver. After only three days of development, we had a working driver and a kernel plug in for interrupts”
