System Navigator for AMD Geode™ GX and LX Processors

The System Navigator is designed to support the special features and integrated peripherals of the AMD Geode™ GX and Geode™ LX processors. The Geode GX processor family consists of:
AMD Geode™ GX 466@0.9W processor
AMD Geode™ GX 500@1.0W processor
AMD Geode™ GX 533@1.1W processor

The System Navigator probe also supports the Geode LX processors:
AMD Geode™ LX 700@0.8W processor
AMD Geode™ LX 800@0.9W processor
AMD Geode™ LX 900@01.5W processor

On-Chip Instrumentation (OCI®) extensions for software debug and system testing have been jointly developed with AMD and are integrated into the processor. These OCI features allow FS2 to provide a powerful debug tool with advanced features at a competitive price.

The System Navigator tool is used for hardware testing and integration, BIOS development, and other firmware/software testing. In addition to hardware and software breakpoints, processor run control, and access to all the CPU registers and coprocessor registers, the FS2 System Navigator has on-chip trace features. Trace information is decoded and displayed as executed instructions. Trace is captured in an on-chip memory (128 x 64-bit frames). The trace window displays disassembled instructions interspersed with special messages such as interrupts and exceptions.

The The System Navigator is contained in a compact chassis that connects to the target system using a
14-pin debug connector and optional off-chip trace connector. The System Navigator runs on a Windows® 2000/XP PC or Linux PC over a USB 2.0 port or optional 10/100 Ethernet connection. The GNU-based source debugger program GDB is included and provides the user with an easy-to-use source level interface in addition to the assembly level debug user interface.
