JTAG ICE, PARTNER-Jet, High-speed multi-function JTAG ICE

To demonstrate the superior performance of the PARTNER-Jet, KMC conducted tests using an T-Engine MC9328MX1 (Model TTM101-001 with ARM920T core), one of the most popular development platform for ARM920 series supplied from Yokogawa Digital Computer Corporation. T-Engine is an effective cross-platform measure of system performance because it is widely supported by several ICEs. All tests was done with this board.
KMC ran the benchmark tests using commonly used ICE operations, including file download and upload, step execution, FLASH ROM writing and debug information loading. We measured the time to execute each action or operation and compared the performance of all actions.

Settings for each ICE is shown below.  JTAG clock frequency is set manually so that each ICE can debug the target board at the highest speed.  I/O system on the target board is initialized after activating debugger.

• Note
• PARTNER-Jet has a functionality to measure comsumption time of a command and the measured time is as accurate as within 1/100 second.

To demonstrate the superior performance of the PARTNER-Jet, KMC conducted tests by downloading a 4MB binary file into target memory and measured time for the operation. For upload, we transferred 4MB of data on the target memory to host machine. We measured a comsumption time with a stopwatch from a command entry to the next command prompt in the command window. We also ensured that the time was accurate enough to match the one entering command from GUI window.

To demonstrate the superior performance of the PARTNER-Jet, KMC conducted tests by downloading (writing) a 1MB binary file into target FLASH memory and measured time for the operation. The test was done after clearing (zero-ing) the target FLASH memory. Furthermore, if the ICE allows to allocate working area in user RAM space, time using that working area is also measured. The time measurement was done is the same way with downloading a binary file.

To demonstrate the superior performance of the PARTNER-Jet, KMC conducted tests by stepping through small NOP loop and measured time required for 1,000 steps in machine language level. The program code is as follows:

The initial program counter value was set to 0x08100000. The time measurement was done is the same way with downloading a binary file.

KMC conducted tests by downloading a debug information of a Linux kernel (vm.out with debug information, approx. 27MB in size) to debugger and measured time for the operation.
