Reference designs show low-complexity FPGAs for HMI solutions

February 17, 2014 // By Graham Prophet
Lattice Semiconductor has released USB3 and HMI solutions that it will demonstrate at the forthcoming Embedded World exhibition in Nuremberg, where the company will also present papers on MIPI Interfacing.

Embedded designers can use low-power, low-cost FPGAs (Field Programmable Gate Arrays) to overcome the challenges of implementing MIPI interfaces, Lattice asserts. HMI-on-a-Chip (HOC) is a complete Lattice FPGA-based single chip HMI reference design demonstrating touch screen based HMI solutions. The solution is scalable and can be implemented using Lattice’s family of MachXO2 or MachXO3 FPGAs as well as LatticeECP3 devices. You get, the company claims, scalability, high-end graphics, fast response times, and ease of HMI design; adding that ”unlike microcontroller-based solutions, the Lattice HMI solution is editor-based, so no programming or operating system expertise is required.

The Lattice USB3 Video Bridge reference design addresses emerging applications in consumer, video broadcast, machine vision, and surveillance applications built around the new USB3 interface. USB3 is amongst the preferred formats for reasons of flexibility, cost, size and availability of standard parts, the company adds; since image sensor, SDI, or HDMI video and audio formats are different from native USB3 data format, a bridge design is required, and low cost, low power FPGAs are ideal for this application.

Lattice will demonstrate the new USB3 and HMI solutions at embedded world at the Arrow Electronics booth (Hall 5/Booth 370) and Future Electronics booth (Hall 4A/ Booth 110). Ted Marena, Lattice’s director of product marketing for MachXO Families, will present two papers at the Nuremberg conference that address the emerging use of the Mobile Industry Processor Interface, or MIPI standards, within the context of embedded designs and specifically for display applications. Marena will discuss how small-form factor FPGAs with their low power and low cost can help designers to overcome the system design challenges that must be addressed when integrating low-cost, high-reliability components designed for smart phones and tablets.
