System Navigator™ Probe
for 8051 Microcontroller Cores

The System Navigator™ probe is designed to support the special features and integrated peripherals of 8051 cores from several IP vendors. The System Navigator probes are available for the following cores and processors:

Special "silicon hooks" for System-on-Chip (SoC) development have been integrated into the synthesizable IP model for the core. This OCI® (On-Chip Instrumentation) logic provides a powerful debug tool with advanced features at a competitive price.

MIPS Technologies' System Navigator probe hardware is contained in a compact chassis that connects to the target system using a standard 10-pin debug connector. It requires access to only four pins in the core processor. The system runs on a Windows® 7 (32-bit or 64-bit) or Windows® XP (32-bit) PC over an USB 2.0 or optional 10/100 Ethernet port. A graphical, source-level debugger program provides an intuitive, easy to use interface. A software driver is included for use of the probe with the Keil µVision (UV3 or UV4) software debugger interface.
