High-Performance JTAG Emulator

The Corelis CodeRunner emulator utilizes the industry standard IEEE-1149.1 JTAG Test port to access the internal debug resources available on the microprocessor. Since the boundary-scan logic of the processor is separate from the core processor logic itself, this access mechanism allows complete non-intrusive access to all processor resources. Thus, no interrupts, no RAM, no ROM, and no registers need to be assigned for debug purposes and no ROM based debugger or loader program is required. At the same time, no peripheral resources such as serial ports are needed to communicate with the emulator/debugger.

In addition to these benefits, the use of the JTAG interface also ensures that RAD750 microprocessor access is maintained even when the processor ‘hangs’ or otherwise runs out of control. Programs and data can be downloaded to any part of the system RAM through the JTAG port without the need for a resident loader program.

The JTAG interface is a simple, five-wire interface that connects to the target system via a flexible ribbon cable, and does not require removing the processor. The JTAG interface is controlled by a Corelis high-performance NetUSB-1149.1/E JTAG controller.

CodeRunner Debugger

The CodeRunner emulator includes a powerful source-level debugger with a multi-window environment, allowing the developer to view source code, assembly code, variables (both local and global), memory, and register locations at the same time. It also supports the concurrent debugging of targets with multiple CPUs, providing the capability to display windows for each CPU on the screen simultaneously.

RAD750 Standard TAP (COP) Pin Assignments

CodeRunner provides full source-correlated debugging, allowing the user to display the source for a particular line of assembly code and vice versa. CodeRunner includes a modern integrated development environment (IDE), and features a very straightforward and user-friendly interface. Anyone familiar with the usage of source-level debuggers will master CodeRunner’s powerful features quickly, reducing the learning curve.

CodeRunner works with all popular C/C++ cross-compilers that generate ELF/ MDEBUG, ELF/Stabs, or ELF/MDEBUG & stabs debug information. The user has the option to automatically load all debug symbols along with the executable, and these symbols will be displayed alongside of each line of assembly code.
