Top Level Design

The first component of the IP Core is the Top Level Design. It is an interface between external hardware (imager, sensors, GigE PHY) and FPGA internal data processing. We deliver this module as VHDL source code that can be adapted to custom hardware.

Video Acquisition Module

The Video Acquisition Module of the reference design simulates a camera with a test pattern generator. This module is delivered as VHDL source code, which has to be replaced by a sensor interface and pixel processing logic in the final camera design.


A Framebuffer interfaces to the FPGA vendor specific memory controller. The framebuffer allows for frame buffering and image packeting. This is necessary to implement the packet resend function. This module typically uses external memory, but could also be realized with limited functionality by the FPGA’s internal memory.

GigE Packet Composer

The GigE Packet Composer generates the final stream packets with all headers required by the GigE Vision transport layer. The GigE Packet Composer sends all data to the Ethernet MAC and implements the high-speed GigE Vision Streaming Protocol (GVSP).


A MAC component interfaces to the low level transport layer technology and physical layer. It is available for different speeds from 1 Gbps up to 10 Gbps and may support packet stamping according to the IEEE1588 protocol.

GigE Vision IP Core Description

GigE Vision is a standard communication protocol for vision applications based on the well-known Ethernet technology. It allows easy interfacing between GigE Vision devices and PCs running TCP/IP protocol family. Sensor to Image offers a set of IP cores and a development framework to build FPGA-based transmitter products using the GigE Vision interface. Due to the speed of GigE Vision, especially at speeds higher than 1 Gbps, senders require a fast FPGA-based implementation of the embedded GigE core. The GigE Vision core set is compatible with AMD 7 Series devices (and newer), Intel Cyclone V devices (and newer) and Microchip PolarFire.

Supplied Reference design

Fully-functioning Reference Design: S2I’s FPGA solutions are delivered as a self-contained, fully-functioning reference design that is running on an agreed common platform along with FPGA IP Cores. This minimizes development time and allows for top-notch performance at a small footprint, while leaving enough flexibility to customize the design. Sensor to Image cores are compact and leave enough space in the FPGA for your application.

FPGA Integrated CPU

An FPGA integrated CPU design (MicroBlaze, NIOS, ARM, Risc V) is used for several non-time-critical network and configuration tasks. It also implements the GigE Vision Control Protocol (GVCP). This software is written in C and can be extended by the customer.

Custom Configuration

Some parts of the design are delivered as binary files only (for example the GigE Vision control protocol library), while other parts are delivered as source code. The design framework comes with all the necessary design files and cores, Vivado or Quartus project files. It is configured as a GigE Vision camera system with a configurable test pattern generator. This system is delivered as a reference design for an off-the-shelf evaluation board. The reference design uses the AMD or Intel development tools (not in the scope of delivery).

C Source Code for software library

The embedded GigE Vision library of the GigE Vision IP Core can optionally be delivered as source code. This is useful to extend functionality for rarely used optional GigE Vision features or to better tailor hardware requirements. An additional driver enables the use of Linux on the device.

IEEE1588 Support

The GigE Vision IP Core has the option to synchronize its timebase with an external IEEE1588 time source. This is necessary for precise timed triggering without extra cabling. When no external time source is available, the system itself can act as a time source.

GenDC support

The GigE Vision IP Core has the option to support the powerful and very flexible GenDC payload type. This is useful to transfer complex data structures often used in 3D applications.

Low Latency ACTION Command Decoder

The GigE Vision IP Core has the option for a hardware-implemented decoder for the GigE Vision ACTION Command. This allows low latency, low jitter ad-hoc triggers.

Multistream Support

The GigE Vision IP Core has the option to transfer multiple data streams over a single link. This is useful to transfer unrelated data from different data sources over one cable.
