Abstract | |
| The Local Trigger Processor (LTP) receives timing and trigger signals from the Central Trigger Processor (CTP) and injects them into the Timing, Trigger and Control (TTC) system of a sub-detector front-end TTC partition. The LTP allows stand-alone running by using local timing and trigger signals or by generating them from memory. In addition, several LTPs of the same sub-detector can be daisy-chained. The LTP can thus be regarded as a switching element for timing and trigger signals with input from the CTP or the daisy-chain, from local input, or from the internal data generator, and with output to the daisy-chain, to the TTC partition, or to local output. Finally, in combined mode several LTPs can be connected together using their local outputs and local inputs to allow stand-alone running of combinations of different sub-detectors. | |
