A system and method of performing diagnostic tests of computer devices, including but not limited to memory, while the operating system is running, is presented. From picking the seismic records of one or more events for different source-pickup pairs associated with the weakest offset of a seismic acquisition device, the geometry of the events is predicted for the total range of offsets of the acquisition device and for different velocity values taken around a reference layer velocity, by means of kinematic inversion and modelling techniques. , an effluent from a semiconductor processing tool that employs corrosive fluoro species such as HF, NF3, etc. While one of the signals processed from a column is being stored in a first memory bank, signals previously processed and stored in a second memory bank are being readout of the storage locations and provided downstream for further processing. The first and second field effect transistors are High Electron Mobility Transistors.
