![]() 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. The JTAG interface is controlled by a Corelis high-performance NetUSB-1149.1/E JTAG controller. 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. 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. 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. At the same time, no peripheral resources such as serial ports are needed to communicate with the emulator/debugger. 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. 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. The Corelis CodeRunner emulator utilizes the industry standard IEEE-1149.1 JTAG Test port to access the internal debug resources available on the microprocessor.
