Actor | Description |
---|---|
DAS | Data acquisition source. Interface for acquiring data from the TDD. |
DAT | Data acquisition transformation. Sends packed pairs of samples to the GPU and unpacks the samples on the GPU. |
DVL | Determine voltage level. Sorts the input data in the current window and determines high and low voltage thresholds. |
STR | State representation. Converts samples that encapsulate voltage values into digital form (high/low voltage states). |
FSM | Finite state machine. Determines voltage transitions from high to low voltage states or low to high voltage states. |
TRT | Compute transition time. Computes the transition time for each voltage transition in the current window. |
RE | Rough estimation. Derives a preliminary estimation of the clock period. |
RRE | Refine rough estimation. Refines the rough estimation of the clock period to improve its accuracy. |
LFT | Linear fitting. Further refines the estimated clock period with linear fitting. Computes time interval errors (TIEs) using the refined clock period estimate. |
TSD | Compute TIE standard deviation. Computes the standard deviation of the TIEs for the current window. |
GCC | GPU to CPU data transfer. Transfers clock period result from GPU memory to CPU memory. |
GCT | GPU to CPU data transfer. Transfers TIE standard deviation from GPU memory to CPU memory. |
SKC | Corrected refined estimation sink actor. Produces the result of the corrected refined estimation for the recovered clock period. |
SKT | Standard deviation of TIE sink actor. Produces the standard deviation of the TIEs. |
