Overview

The DB1892AXI RGB to CCIR 601 / CCIR 656 Encoder interfaces RGB data along with synchronization signals from a LCD Controller (or any LCD display timing & control unit) to a TFT LCD Panel by-way-of a CCIR 601 / CCIR 656 interface.

Figure 1 depicts the system view of the DB1892AXI RGB to CCIR 601 / CCIR 656 Encoder IP Core embedded within an integrated circuit device. The DB1892AXI RGB to CCIR 601 / CCIR 656 Encoder accepts 24-bit RGB data and VSYNC, HSYNC, and DE synchronization signals and converts the RGB & sync signals to the CCIR ITU-R BT.601 & BT.656 standards, for driving a CCIR 601 / CCIR 656 compliant LCD panel.

The DB1892AXI is a system-level IP Core which optional interfaces to the ARM AMBA AXI fabric for programming of internal parameters. The DB1892 is offered with AHB, OCP, PLB, and Avalon fabrics as options, as well as no fabric interface with hard-coding of the video transformation parameters.

The DB1892 interfaces to Digital Blocks’ DB9000 TFT LCD Controller, for a full system solution of transforming Frame Buffer RGB data to CCIR 601 / CCIR 656 standard video.

Key features

  • The DB1892 performs the following video signal processing functions:
  • Color Space Converter - Inputs RGB 24-bit data and sync signals VSYNC, HSYNC, & Date Enable from a LCD Controller. The Color Space Converter converts the 4:4:4 sampled RGB pixels to component luma and chroma digital video 4:4:4 YCbCr.
  • Chroma Resampler - The Chroma Resampler down converts the 4:4:4 YCbCr to 4:2:2 YCbCr, in order to meet the ITU-R BT.601 requirements of the ITURBT. 656 Encoder.
  • BT.656 Encoder - Encodes the 4:2:2 YCbCr component digital video with synch signals to conform to the ITU-RBT.656 digital coding standard.

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.
