Overview
The Display controller (DISP) provides a parallel digital RGB (red, green, blue) and signals for horizontal, vertical synchronization, pixel clock and data enable as output to interface directly to a variety of LCD and TFT panels.
The controller supports multiple data formats, and adapts to RGB or BGR. The user can configure the pixel clock frequency according to the screen resolution and frame rate. DISP has four interrupt signals to indicate the current working status.
The dithering pseudo-random technique is used to add a small random value (threshold) to each pixel color channel (R, G or B) value, To adapt to panels with a bit width lower than 24bits.

In this article we provide an introduction to DP, talk about the various factors that IC designers will want to consider when integrating the DP functionality into their SOC, and present at a high-level the solutions Silicon Creations provides in this area.
The whys and hows of secure boot
With the proliferation of Internet of Things (IoT) devices, which now span just about every walk of life, from smart cities to wireless jewellery, the need to prioritize security in IoT-style embedded systems has never been greater. The secure boot process is a vital first step in securing any embedded system, a necessary part of your application’s anti-malware fortress. Let’s take a look at the pros and cons, with a focus on one of the most popular processors in electronics – the i.MX6.
Motion Picture: a Reality on Emulation Platform
In present day’s situation, whenever we are in the phase of designing a cluster SoC, we have no reliable way of verifying our design in real case scenarios, or showcase the possibilities of our design through any demos. This, sometimes, paves way for critical design bugs which requires re-spins/cuts.
Sequential clock gating maximizes power savings at IP level
In this paper we talk about design exploration using the PowerPro tool. For analysis of power optimization based on this tool, we have included Advanced Driver Assistance System (ADAS) and cluster IPs with high speed processing requirements. These IPs have multiple complex operation requirements within a clock period, making them ideal candidates for power saving. The IPs under consideration are image processors, high-speed bus fabrics for a memory controller, display controllers, and video codecs.
