A central component of the SiRFatLas IV chip is the PND-on-a-chip chip solution. This solution takes information from GPS baseband, low-noise amplifier and radio frequency circuitry. This information is embedded on the chip. This solution also incorporates an ARM11 processor, which helps improve graphics performance. This unique technology is broken up by market: entry-level, mid-level and high-level.
The entry-level PND-on-a-chip solution gives you a combination transceiver and USB 2.0 OTG high-speed controller. This is the simplest form of the solution. All of these solutions are sold under the BCM4760 PND model, but the features are different depending on the market. The mid- and high-level markets offer more usability and much more exciting features, but you'll pay a lot more for these privileges.
The mid-level market PND chip solution is designed for the 3D market. It allows you to quickly pull up both 3D landmarks and maps. This chip solution is specifically designed to work with different connectivity devices, including your WLAN and Bluetooth-enabled devices. This chip solution is an advancement over past solutions since it's so much faster. Plus, you get a whole bunch of new features, including the ability to look at your photos and listen to your favorite music.
Things get even more interesting with the high-level chipset solution. This PND is designed to work with your mobile devices. It comes with the VideoCore series of multimedia co-processors. What this means is that your graphics don't look flat like they do on most GPS devices. These co-processors even allow you to watch HD videos. You can also record audio and video with your GPS device. Graphics are faster on this device, ensuring that you won't be waiting forever to pull up a map.
