2 TECHNICAL DESCRIPTION
2.1 Bluetooth™ GPS Receiver architecture
The NAVI-XS POI OEM GPS receiver from FALCOM is a new OEM product that
features the SiRFstarIIx single chipset. The core of NAVI-XS POI is comprised of the
GSC2x - that includes the Digital and RF in a single chip. The flexibility of the core
allows the core processing engine and memory to be reconfigured to track up to 12
satellites. The core of NAVI-XS POI contains a built in sequencer, which handles all
the high-rate interrupts for GPS tracking and acquisitions. After initialization, the
receiver handles all the time critical and low latency acquisition, tracking and
reacquisition tasks of GPS autonomously. The on-chip SRAM size is 1-Mbit memory
that is used for instructions. The internal XTrac 2.0.2 firmware stored in the 8 Mbit
FLASH completes the package providing flexible system architecture. The data
delivered from GPS receiver will be sent via Bluetooth™ antenna to the host device
(to the connected Bluetooth™ enabled device).
