Tiny FPGA Modules

FDB Series: Tiny FPGA Modules for High-Performance Embedded Systems

The FDB series includes FDB16 (49 × 54 mm), FDB27 (58 × 58 mm), and FDB66 (58 × 58 mm). These modules rank among the tiniest FPGA modules available on the market today, making them ideal for custom PCIe-based or standalone, space-constrained systems. Moreover, their ultra-compact form factor enables seamless integration into embedded designs while maintaining full performance capability.

Performance and Memory in the FDB Tiny FPGA Modules

Each FDB module uses an Altera Arria 10 GX FPGA, supports up to 10 GB DRAM at 24 GB/s, and includes 16 × 14.2 Gb/s transceivers (10 full duplex plus 2 RX only). Consequently, this tiny FPGA platform delivers high performance at a competitive price. In addition, the robust design supports mission-critical tasks and long-term deployment. Therefore, the platform suits applications that require efficiency, durability, and scalability.

Real-Time Image Processing

Gidel’s FDB ultra-light FPGA modules enable real-time image acquisition, preprocessing, and enhancement directly at the edge — ideal for drones, gimbals, UAV payloads, robotics, and compact embedded systems.
All processing is powered by Gidel’s modular real-time preprocessing, enhancement, and advanced compression IPs (.JPEG, Lossless, Quality+).

Inline enhancement features include:

• High Dynamic Range (HDR) – Captures superior details in high-contrast lighting conditions.

• White Balance – Maintains color accuracy across variable lighting conditions.

• Dynamic Luminance Balance – Preserves consistent brightness under changing illumination.

• Gamma Correction – Optimizes brightness and contrast for improved clarity.

Real-time compression with Dynamic ROI delivers:

• Extended recording times without compromising quality.

• Lower transmission bandwidth for efficient data handling.

• Accelerated offline compression, reducing storage needs and post-processing time.

Integrated Vision Architecture for Embedded FPGA Processing

Gidel’s vision architecture, implemented within the FDB tiny FPGA modules, supports both the InfiniVision multi-camera vision system and the ProcFG deterministic image acquisition system. Together, they address critical embedded vision challenges, including bandwidth handling, synchronization, connectivity, and system scalability.

InfiniVision enables flexible, synchronized multi-camera acquisition across large sensor arrays, while ProcFG provides a deterministic acquisition model optimized for fixed timing, guaranteed frame capture, and line-scan–oriented pipelines. This architectural flexibility allows the FDB platform to manage multiple high-speed data sources, merge parallel sensor inputs, and maintain predictable real-time behavior.

On-module FPGA memory, advanced buffering, and deterministic dataflow control ensure stable acquisition and enable real-time image processing. As a result, FDB modules deliver reliable and predictable performance, even in compact, space-constrained, high-resolution embedded systems.

Flexible Integration Options

The FDB modules adapt to diverse integration needs. They can operate as standalone embedded processing engines inside miniature systems or as part of a fully customized solution incorporating on-board FPGA image enhancement, real-time compression, precise multi-sensor synchronization, and advanced I/O control. As a result, the FDB series provides exceptional flexibility and scalability for any embedded imaging or vision architecture.

SDK, Development Tools, and Integration

The FDB modules are supported by Gidel’s SDK with intuitive GUIs and APIs for fast system integration.
The ProcVision Suite provides advanced FPGA programming, debugging, and validation tools, enabling rapid customization of data flows and real-time processing pipelines.

In addition, the FDB series features an advanced multi-port DRAM controller that splits memory into
up to 16 parallel logical banks with simultaneous access. Each module is supplied with a
PCIe carrier board and development utilities, allowing engineers to begin testing immediately.
As a result, development cycles are shorter, reliability is higher, and time-to-market is significantly improved.
