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 Adaptive Clocking Adapter handles these
changes in real time, maintains synchronization. It 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.
