Lattice has updated its mVision solution stack to support 4K video data processing and LPDDR4 memory to deliver higher quality ISP performance.

Lattice Semiconductor Corp. has updated its Lattice mVision solution stack to support 4K video data processing and LPDDR4 memory to deliver higher quality image signal processing (ISP) performance. This allows developers to quickly implement popular high-speed communication and display interfaces to accelerate embedded vision performance with class-leading low power consumption for Edge applications including machine vision, robotics, ADAS, video surveillance, and drones.

Industry analyst Bob O’Donnell with TECHnalysis Research noted, “LPDDR4 memory provides device designers with a great range of different capacities/densities, speeds, and power requirements that can be matched to specific applications. Because of its low power nature, LPDDR4 memory is particularly well-suited for embedded and machine vision in battery-powered devices or other applications where thermal management is a challenge.”

“Embedded and Machine Vision applications enable compelling new user experiences across Industrial, Automotive, and Consumer markets. But supporting vision applications at the Edge requires developers to achieve a delicate balance between providing the processing performance these applications require while fitting within the design’s power consumption and physical footprint constraints,” said Mark Hoopes, Director of Industrial and Automotive Segment Marketing, Lattice Semiconductor. “Our mVision stack simplifies and accelerates embedded vision solution development, and our latest release leverages the class-leading features of Lattice Nexus FPGAs to support high performance interfaces and faster processing at low power.”

The stack’s expanded capabilities include support for the LPDDR4 DRAM memory standard. With up to eight programmable SERDES lanes capable of speeds up to 10.3Gbps, Lattice Nexus platform devices deliver the highest system bandwidth in their class to enable popular communication and display interfaces like 10 Gigabit Ethernet, PCI Express, SLVS-EC, CoaXPress, and HBR3 DisplayPort (at up to 8.1Gbps per lane).

The latest reference designs help developers convert legacy video standards commonly used in industrial applications to the more widely-used MIPI standard. The new reference designs include MIPI to parallel conversion and vice versa; MIPI CSI-2 to LVDS conversion; and 1-to-N MIPI duplicator.

It also features new Lattice ISP support for Lattice Nexus FPGAs. New ISP support from Lattice partner Helion enables high resolution, high frame rate UHD cameras.
