Cyclone III FPGAs in Automotive Applications
Automotive-grade Cyclone® III FPGAs offer an unprecedented combination of low cost, functionality, and low power to meet next-generation automotive application requirements. Also available are a rich set of software, intellectual property (IP), reference designs, and development kits to accelerate product development and lower risk.
Challenges
Often automotive prototype and design cycles span several years. Designers and systems must be flexible to support emerging/changing consumer demands such as a new multimedia interface that may not have been popular during design concept but is a must-have feature at product launch. This flexibility requirement often rules out many ASIC or ASSP implementations. There is often the need to include varying feature sets to differentiate between affordable and luxury automobile models. There is also a plethora of automotive networking standards to contend with. The growing demand for in-cabin multimedia is pushing digital signal processing (DSP) and graphics processing requirements beyond the limits of traditional DSP devices. Product life cycles can be anywhere from a few years to decades with long aftermarket service requirements.
Solution
Automotive-grade Cyclone III FPGAs enable automotive OEMs to be flexible up to the last minute to accommodate feature needs that are changing faster than typical automotive design cycles. The flexibility of Cyclone III FPGAs enables you to create a single platform that you can use for multiple product lines. Pre-verified intellectual property (IP) is available for Cyclone III FPGAs to easily support all of the latest automotive networking standards such as controller area network (CAN), media-oriented system transport (MOST), local interconnect network (LIN), and FlexRay. Automotive products using Cyclone III FPGAs can also be updated in the field after the car is sold. Abundant multipliers and memory in Cyclone III FPGAs can be used to meet the growing appetite for high-quality video in infotainment features. Fast parallel configuration and automotive temperature support of up to 125°C (junction) enable Cyclone III FPGAs to meet stringent automotive system requirements.

Typical Navigation System
A navigation system is one of the key applications within the automotive space that utilizes a fair amount of graphics processing. The graphics processing complexity varies from a simple turn-by-turn (TBT) navigation to a more sophisticated 3D navigation system. Graphics processing requires the computation of numerous algorithms such as scaling, filtering, and alpha blending. Unlike digital signal processors or ASSPs, Cyclone® series FPGAs are better suited to perform these computationally-intensive algorithms because they can handle multiple instructions in a single clock cycle.
Figure 1 shows a low-cost graphics implementation in an Altera® Cyclone III FPGA. The video-in can be a BT.656 input (YUV 4:2:2), with a color space converter (CSC) to output RGB. The memory interfaces supported include: SDR, DDR, and DDR2. The Altera Nios® II 32-bit embedded processor is primarily used for graphics processing (line draw, frame creation) and provides additional control functions. Graphics hardware acceleration can include functions such as BitBlt (copy object into frame buffer, 2D-DMA transfer, possibly with blending). Alpha blending can have multiple channels. Cyclone III FPGAs are capable of supporting LVDS graphics output for remote display applications.
