Navigation Devices

Navigation devices are increasing in popularity everywhere, from cars to mobile phones, helping people find the correct direction to a particular location or destination from a given starting point. Advanced navigation devices also assist the disabled (such as the blind) by reading out directions and providing other useful features. Navigation devices today rely on satellite-based services, such as Global Positioning System (GPS), GLONASS, or Galileo to function, but may also use other connectivity solutions, such as 3G and Wi-Fi, depending upon the capabilities built into the device.

The GPS system uses data from a network of satellites to obtain location information anywhere on or near the surface of earth. The 21st century has seen a remarkable increase in the penetration of GPS based navigation services, primarily due to advances in the electronics and semiconductor technology space, making the availability of GPS services on devices, such as mobile phones, possible.

The GPS technology has evolved significantly, from the simple devices that showed people their geographical locations, to the latest ones that possess Internet access capabilities and allow two-way communication. GPS has also been deployed in the marketing segment, through the concept of "GPS Advertising" - sending custom advertising messages to select GPS receivers.

Samsung, a global leader in the electronics industry and a trusted brand in the semiconductor space, is the preferred supplier for several of the world's top companies and OEMs in the navigation devices industry. Samsung components, such as memory, displays, display drivers, and application processors, power some of the most advanced and most capable navigation devices in use today. OEMs trust Samsung to realize their most advanced designs and bring them to market in the shortest time and with the lowest costs.

The following illustration shows the architecture of a typical navigation device.

Application Processors

As shown in Figure 1, the main components of the device are the application processor, the memory subsection, and the display driver IC (DDI). Samsung is the leading provider of high-quality components and devices across all these segments.

For deployment in navigation devices, Samsung has a complete range of advanced, low-power application processors that are designed for exceptional performance with leading-edge features, along with a comprehensive suite of software development and support tools. Currently, Samsung offers application processors with the following cores (listed in increasing order of capabilities):

  • ARM 7 Series
  • ARM 9 Series
  • ARM 11 Series
  • Cortex A8 Series
  • Cortex A9 Series

Samsung application processors are the industry's most advanced SoCs and have the highest number of features integrated on the silicon, resulting in the minimum number of external components required, reducing the time-to-market for the product. Some of the important advantages of using Samsung application processors in designs for navigation devices include:

  • Highly optimized ARM-based cores:
    Samsung application processors use industry-standard ARM cores, which are the benchmark for mobile, portable, and low-power computing and communication devices.
  • Multiple memory support:
    Samsung application processors support all major types of memory used today, such as mDDR (mobile DDR) and LPDDR (Low Power DDR), as well as the latest and newest memory technologies, such as moviNAND.
  • On-chip peripherals:
    Samsung application processors include an array of several standard peripherals on the chip, eliminating the need for external interfaces, saving design costs and time. Examples of integrated peripherals include a 24-bit true color LCD controller, AC-97 audio codec, IrDA codec, and USB 2.0 OTG controller.
  • Extensive software support:
    Samsung application processors come with a comprehensive suite of software solutions, such as Board Support Packages (BSPs), which reduce software and firmware development costs and time for the final application. Additionally, these packages also make it easy to port applications developed for one family of Samsung processors (such as those based on the ARM 9 series) to a higher family (such as the Cortex A9 series processors).

Work with a leader

A leading provider of DRAM including 20nm-class and 30nm-class solutions, Samsung delivers the latest memory technology, to meet or exceed design requirements. Samsung Mobile DRAM technology provides significant power savings compared to previous-generation modules, while improving performance, for the best in navigation device designs.

Display Driver IC

Navigation devices also include a display driver IC (DDI), whose function is to control features related to the device's LCD display. The DDI is mapped to the device's main application processor (see Figure 1) and it feeds data to the LCD unit.

The display is one of the most important outputs for the device, so it is vital that the performance and quality of the device's display subsystem remain above a certain minimum threshold at all times for a good user experience.

Samsung is one of the top innovators of LCD and LED display technology (including the latest touchscreen technologies), and has been at the forefront of providing the most advanced DDI solutions for navigation devices. Samsung provides DDI solutions for displays of varying resolutions, from basic VGA (640 x 480) to WUXGA (1920 x 1200), and beyond.

Samsung DDI solutions are the industry-standard for navigation devices. Some key benefits of using Samsung DDI solutions in these devices are:
Separate and dedicated DDI reduces display-related processing load for the system's application processor, enhancing the overall performance for the device.
A DDI module ensures the availability of advanced display controls, such as enhanced contrast correction for the displayed content.
The DDI module can be programmed to turn the display off after a certain period of user inactivity, extending the battery life in portable and handheld navigation devices.

MCP

MCP, or multi-chip package, is not a type of memory, but rather a form of packaging memory chips to reduce the area they occupy, and increase their available densities (per chip). An embedded device, such as a navigation device, may use a combination of several memory types, such as NAND flash, mobile SDRAM, and mobile DDR SDRAM. MCP introduces the concept of unifying multiple types of memory chips onto a single substrate, enabling the rest of the device modules to view the memory subsection as a single, unified "block". Within the substrate, the memory devices may be connected using a variety of techniques, such as die-to-die bonding or die-to-frame bonding. This technique significantly improves the performance of the device's memory subsection and reduces the board space used due to the integration of multiple chips onto a single substrate. Samsung has a vast portfolio of MCP products for a variety of solutions, such as mobile phones and GPS receivers.

eMMC

The eMMC standard describes an architecture that consists of an embedded storage solution with an MMC interface, a type of flash memory, and a controller, all integrated in a single BGA package. eMMC capable embedded memory devices contain not only a data storage element (such as NAND flash memory), but also a controller for the storage element integrated on the same silicon die. This results in several advantages, such as reduced development time and easier integration of the memory block in the overall system. Ultimately, this leads to a much shorter time-to-market for the product. Samsung is one of the main providers of eMMC technology across the world.
