With this new capability for Green Hills' MULTI® Debugger, developers can view multiple threads in separate debugger windows, which makes debugging of multithreaded applications easier and far more intuitive.

Each thread's source display window has a distinctive background color and displays the thread's name and current state. Users can view call stack displays and local variable data display windows for any or all threads. If the system is stopped when a displayed thread is currently executing, that thread's run controls become active.

"MULTI's new multithread debugging capability picks up where conventional source debuggers leave off," remarked John Carbone, vice president of marketing at Green Hills Software. "The ability to simultaneously debug several ThreadX program threads in separate debug windows gives programmers a far clearer view of thread interaction and execution, thus making it much easier to understand and debug today's increasingly complex multithreaded embedded programs."

The ThreadX RTOS is the most technically advanced real-time multitasking solution on the market today. Combining a picokernel design with fast timers and a high-speed preemption-threshold mechanism, ThreadX features a context switching time of less than two microseconds on a 40-MHz PowerPC 860 processor. The ThreadX picokernel is also memory stingy, requiring just 5 kbytes for a minimum footprint.

MULTI and ThreadX are available from Green Hills Software for a wide range of 32-bit microprocessors used in embedded development, including the PowerPC 821/860, 750, CPU32,ColdFire, MIPS, SH, 68K, MCORE, ARM7TDMI, TriCore, and StrongARM processor families. Host/target connectivity options include a wide variety of BDM and JTAG OCD (On-Chip Debugging) solutions, EST's visionICE, HP's Emulation Probe, ARM's EmbeddedICE, and various ROM Monitors.
