QuickLogic - The ArcticLink III CUB System Allows Easy Integration of Display Bridges into Customer Systems

ENP Newswire - 12 February 2014

Release date- 11022014 - System designers are faced with many obstacles during the design of a smartphone or tablet, one of the toughest being integration of key components such as display bridges.

QuickLogic's CUB (Customer Use Board) system allows designers to insert QuickLogic's ArcticLink III VX CSSP series of display bridges into the display path of their product, allowing software bring-up and product testing to take place through known-good hardware.

CUB Mother BoardDuring the design process, often physical CPU reference design boards are used for testing and bring-up of prototype hardware. These reference designs are subject to the specifications of the processor, meaning often they only support a single display standard (MIPI-DSI, LVDS, or RGB, for example). As has been shown numerous times through millions of shipping products, often the display chosen requires a different standard, and a bridge device must be used. In this situation, the system designer is often forced to create a custom board(s) that uses the chosen display bridge, a time-consuming, costly, and laborious task. The CUB display bridge reference design system eliminates that need by providing an out-of-the-box solution.

The CUB system is a series of boards that support either a 'blue wire' or direct connection between the CPU and the display. Supporting the entire span of QuickLogic's ArcticLink III VX product line, the CUB system allows display data to flow from the CPU to the display with all requires interface conversion. The CUB system very closely resembles the actual architecture of mass production devices, allowing the system designer to immediately begin work on creating and testing device firmware and software, speeding time-to-market.

In addition to addressing and solving the necessary display bridging need, the CUB system also features the ability to allow designers to test and evaluate QuickLogic's VEE (Visual Enhancement Engine) and DPO (Display Power Optimizer) on their own hardware. With simple instructions (via USB) to the CUB, VEE can be demonstrated, adjusted, and even calibrated for the individual system characteristics. Additionally, through manual manipulation of display brightness and the resulting power savings, DPO's ability to extend system battery life can be proven. Designers are assured, via their own design, of the viewability benefits VEE can provide and can measure actual DPO power savings.

A typical use of the CUB system might occur as follows: a system designer may have a processor board with a RGB display output. However, the chosen display might be a VESA-standard LVDS display. QuickLogic and the customer work to create either a custom PCB board that would plug directly from the processor board's RGB connector into the CUB main board, or will hand-wire the RGB signal from the processor board directly to the CUB's Breakout Expansion Card.

For customers interested strictly in display bridging, the CUB system can be used with the ArcticLink III BX product line, pin-identical to the ArcticLink III VX, but without VEE and DPO.

The CUB system supports all variants of the ArcticLink III VX, including:
