Cerritos, Calif.Boundary-scan equipment vendor Corelis now has a family of JTAG (Joint Test Action Group; developer of the IEEE-1149.1-1990 standard) emulators for the Raza Microelectronics (RMI) XLR microprocessor. The emulators can be used when bringing-up boards, during driver and firmware development, and for software application debugging. The product is a cooperative effort between RMI and Corelis.
Using Corelis's CodeRunner-XLR JTAG Emulator software, you get source-level debug capability for multiple processors. It effectively partitions individual processor hardware and software resources into a multi-windowed environment. CodeRunner-XLR also provides extensive macro and scripting capability, and it can interpret command files written in a structured C-like language.
CodeRunner-XLR is available with PCI, USB 2.0 (Universal Serial Bus), and Ethernet JTAG controllers.
To meet the needs of demanding throughput applications, these controllers use a high-speed boundary-scan controller architecture based on Corelis's proprietary Turbo Scan Engine. With the ability to implement programming algorithms directly in hardware, and the ability to provide a sustained JTAG test clock (TCK) frequency reaching 80-MHz, boundary-scan controllers such as the PCI-1149.1/Turbo provide high throughput with file download speeds of 1-Mbyte/s when used with the RMI XLR processor.
In-System Flash Programming
Corelis also offers its TAFP (Target-Assisted Flash Programmer). The TAFP supports in-system programming of flash without the need to remove devices from a board, reducing the cost of development. As the name implies, TAFP uses the XLR processor to program these parts; that increases the speed of programming. Both hardware and software personnel can perform programming functions using a graphical user interface.
