Supporting the AI/IoT/DX Era: OKI IDS’s High-Speed Data Transmission Solutions and Advanced Cable Technology

In today’s world, where AI, IoT, and digital transformation (DX) are deeply integrated into society, systems are becoming increasingly advanced in areas such as factory automation, surveillance, and autonomous vehicles. As a result, high-speed and large-capacity data transmission has become essential. Traditional data transmission methods struggle with real-time processing as data volumes increase, leading to performance bottlenecks. To address these challenges, OKI IDS offers high-speed data transmission solutions using FPGA technology.

Why High-Speed Data Transmission Is Needed and the Advantages of FPGAs

Modern systems demand features such as low power consumption, real-time capability, low latency, robustness (durability and long life), high flexibility, and compactness. For example, in autonomous vehicles, real-time responsiveness and minimal latency are critical for avoiding accidents.

To meet these needs, OKI IDS proposes solutions that utilize Field Programmable Gate Arrays (FPGAs), which are programmable logic devices. Compared to CPUs or GPUs, FPGAs can reduce power consumption by 20% to 50% while offering superior real-time performance, robustness, low latency, high flexibility, and compact design—making them indispensable for high-speed communications.

OKI IDS’s Three High-Speed Data Transmission Solutions

OKI IDS provides the following three solutions to meet diverse customer needs. All of these achieve transmission speeds close to their theoretical maximums.

1. I-Gig (GigE Vision-Compatible Solution)

Product Lineup

• "I-Gig TX" (camera side) with options such as lightweight/high-precision PTP versions and customizable versions

• "I-Gig RX" (monitor side)

Demo Example

• Demonstrated with AMD’s Kria K26 SOM, achieving high-speed transmission of 5.1MP 60FPS color images at 5.1 Gbps—ideal for AI inference applications

2. I-TE (TCP/IP Offloading Engine)

I-TE is a TCP Offloading Engine (TOE) that offloads TCP/IP protocol processing from the CPU to the FPGA for enhanced speed.

Features and Capabilities

• Frees CPU resources and achieves near-theoretical maximum speeds (e.g., 920 Mbps for 1 Gbps links, 99 Gbps for 100 Gbps links)

• Provides two communication functions in a single IP: high-speed TCP and general-purpose control communication

• Supports 1GbE, 10GbE, 25GbE, and 100GbE networks

• Parallel processing on the FPGA accelerates time-consuming tasks like checksum calculation

Use Cases

• Imaging systems and surveillance cameras: Supports the increasing bandwidth needs of 4K and 8K high-resolution video transmission

Development Support

• Supports application development on MicroBlaze soft-core processors and Linux applications on Zynq MPSoCs

• Provides design services for MAC/PHY integration and physical device control

3. I-DMAC (PCI Express DMA Controller)

I-DMAC is an intelligent DMA controller optimized for AMD’s integrated PCI Express blocks, enabling high-speed data transfers between main memory and local FPGA/SOC memory without CPU intervention.

Features and Capabilities

• Maximizes PCIe performance without requiring specialized knowledge

• Includes platform-integrated protocol handling, DMA functionality, target access, and peripheral circuits, reducing development time

• Compatible with Windows and Linux device drivers

• Uses a Command Descriptor Table (CDT) for continuous DMA transfer under virtual memory environments without CPU interruption

• Offers two DMA modes: "Normal Transfer" and "Capture Transfer" (the latter enables autonomous continuous transfers ideal for large image data streams)

Use Cases

• Imaging and video production equipment: Transfers large volumes of high-resolution data efficiently

• Data communication equipment: Integrates with OKI IDS’s 100GbE I-TE for high-performance smart NIC solutions

• Now supports PCIe Gen4 x8, improving both bandwidth and energy efficiency

Development Support

• Provides IPs, reference designs, Vivado projects, manuals, and evaluation tools
