REDBUS solution
REDBUS® is a patented communication interface based on standard Ethernet physical transport. It provides a robust and high-speed communication interface for applications like motor control, lighting, fast I/O, and, in general, distributed peripherals on embedded systems.
The REDBUS® MAC allows the interconnection of multiple devices arranged in a ring topology. It instantly repeats the incoming Ethernet traffic to the adjacent system in the ring chain.
The data is organized in time slots and is exchanged on each addressed device during payload transit.
A standard Ethernet PHY device implements the physical layer between the cables and the MAC. This unique topology eliminates the need for external switches. In addition, the simplicity of the software stack enables a wide range of microprocessors with minimal impact on CPU performance.

Features
- High Speed, real-time. The 100 Mbps deterministic communications make it ideal for time-critical applications.
- Robust and reliable. It provides high noise immunity and low EMI, up to 100 meters.
- Cost-effective. It uses only one Ethernet PHY device per node and does not require Ethernet switches. Different kinds of information can be transported in just two pairs of small cables, simplifying wiring.
- Versatile. The interfacing and integration simplicity with processors makes it suitable for use in a large variety of contexts. REDBUS is FPGA-based. It can be optionally combined with your logic on the same device.
- Compact. The REDBUS IP has a low logic density, starting from just 250 Logic Elements.
