Blackhawk JTAG Adaptive Clocking Kit for OMAP

The JTAG Adaptive Clocking Kit (JACK) from Blackhawk is designed to allow JTAG emulators for TI DSPs to synchronize with the adaptive clocking cores of Texas Instruments OMAP devices providing data integrity and increased performance.


What is Adaptive Clocking?

Adaptive clocking is a feature of synthesizable cores, introduced by ARM Ltd. and adopted by TI in their OMAP platform, wherein the input test clock (TCK) is delayed and synchronized with the core clock before producing the output clock (RTCK).

During this delay (synchronizing period) the target core samples Test Data In (TDI), Test Mode Select (TMS), and TCK with the core clock. This delay is variable and changes in real time, which can cause data corruption. The JACK handles these changes in real time, maintains synchronization.


What else do I need to know?

You may find emulator release notes that describe setup changes (workarounds) that are necessary to operate with these adaptive clocking OMAP cores. This usually involves decreasing the output TCK rate of the emulator. While this may seem to correct the problem, the data and clocks will still be unsynchronized with the OMAP core and you sacrifice performance.

The JACK is a simple and easy solution that will allow you to return your emulator's TCK rate back to its maximum frequency providing you with data integrity and increased performance.

For more information on adaptive clocking you can read the Blackhawk Adaptive Clocking Technical Article , visit the TI OMAP web site, or search the ARM web site for " adaptive clocking ".
