High performing GPS solution for high-volume consumer devices with lower processing capacity |
 |
Fastrax Accelerated Software GPS is designed to perform all GPS calculations except the correlation process on the main processor, using only a small portion of the available resources. This allows large savings in GPS hardware cost in consumer electronics devices.
Target Applications
Fastrax's solution is targeting high volume consumer electronic devices, such as cell phones, E911 phones, laptop computers, digital cameras and Personal Navigation Devices. Suitable target applications are high volume consumer devices with low- or mid-end processors that have a capacity for a clock speed of less than 500 MHz.
Functionality and Performance
Fastrax Accelerated Software GPS has even lower MIPS and memory requirements than the Fastrax Software GPS. The CPU load is reduced by performing the correlation process on hardware that is integrated either in the RF front end or in the host processor as shown in the picture on the right side.
The accelerated software GPS is easily portable since it is based on the iSuite architecture, which is originally designed for embedded environments. It is already ported to x86 and ARM processors and to Windows, Windows CE and Linux operating systems.
The Fastrax Accelerated Software GPS is available on FPGA platform (Altera Stratix II) for system emulation and related RTL for silicon integration.
