FS2 System Navigator tools provide best-in-class performance analysis and debug capabilities for 74K-based designs by giving customers full access to the debug features of MIPS([R]) EJTAG, and allowing them to leverage the advanced out-of-order instruction processing, enhanced DSP capabilities and CorExtend[TM] user-defined instructions in the 74K cores.
The System Navigator EJTAG probe can sample the processor PC register at extremely high data rates without impacting the real-time operation of the processor, rapidly profiling large amounts of code.
Core-centric debug features like EJTAG and PDtrace are just part of the FS2 portfolio of system-level debug solutions.
EJTAG vendors that will support the TX4939XBG-400 include Yokogawa Digital Computer, Kyoto Microcomputer Company, Wind River, Inc.
It connects to the target system using the standard EJTAG 14-pin connector for on-chip trace or a 38-pin Mictor connector for off-chip trace capture.
