The VisionICE II is a JTAG emulator for PowerPC and MIPS embedded systems development, delivering hardware-assisted on-chip debugging integrated with Wind River’s Tornado environment. The tool combines a high-speed Ethernet host interface with USB 2.0 connectivity and JTAG accelerator technology to enable real-time trace, breakpoints, memory access, and register control. Performance is optimized through hardware logic that caches common JTAG scan chains, delivering download speeds and debug throughput 4 to 10 times faster than comparable products.
