Overview

The JPEG-D-X core is a standalone and high-performance JPEG decoder for still image and video compression applications. Compliance¹ with the Baseline and the Extended Sequential DCT modes of the ISO/IEC 10918-1 JPEG standard makes this core suitable for interoperable systems and devices. The JPEG-E-X is available for ASIC or AMD-Xilinx, Efinix, Intel, Lattice and Microchip FPGA and SoC based designs.

In addition to decoding standard compliant Baseline and Extended JPEG streams, the core is also capable of decompressing the video payload of many (de facto) standard motion JPEG container formats.

The core is designed with simple, fully controllable and FIFO like, streaming input and output interfaces. Being carefully designed and rigorously verified, the JPEG-D-X is a reliable and easy-to-use and integrate IP.

Enabling AI Vision at the Edge

Computer vision has made tremendous advances in the last several years due to the proliferation of AI technology. The intersection of big data and massive parallel computing changed the way in which machines are programmed to understand unstructured 2D and 3D data, such as video feeds from cameras.

Nextreme Structured ASICs: An alternative for designing cost-optimized ARM926EJ processor-based embedded systems

Traditional IC design options that embedded system designers have had to choose from include fixed hardware devices such as standalone microprocessors, microcontrollers and ASSPs or configurable hardware devices such as FPGAs and cell-based ASICs. In this paper we present a new design option called Nextreme Structured ASICs which provide embedded system designers with a compelling alternative to custom embedded system design.

Generating High Speed CSI2 Video by an FPGA

In this article, we show how fast video streams conforming to MIPI CSI2 rev2.0 over MIPI DPHY rev1.2 can be generated, using VLSI Plus’ SVTPlus-CSI2-F IP core, with simple off-FPGA analog front-end. The high bit rates can be achieved with a relatively slow FPGA clock frequency, trading off FPGA resources for simple timing closure.

Viewpoint: Opportunity to win on different design fronts

Beyond pure process scaling which is necessary to meet today's price, power, and performance goals, chip designers have to grapple with tighter integration and product performance specialities in areas such as integrated power management, image sensing, application-specific data conversion, and enhanced display drivers.
