Accumulation of Waveform Data using Alternating Memory Banks

Номер: US20140075080A1
Автор: Andrew C. Thomson, Anita L. Salmon, Jeff A. Bergeron

System and method for hardware implemented accumulation of waveform data. A digitizer is provided that includes: a circuit, and first and second memory banks, coupled to the circuit. The circuit may be configured to: store a first subset of the waveforms in the first memory bank, accumulate each waveform in a chunk-wise manner, where each chunk has a specified size, thereby generating a first bank sum including a first partial accumulation of the set of waveforms, store a second subset of waveforms in the second memory bank concurrently with the accumulation, and accumulate each waveform of the second subset of waveforms in a chunk-wise manner, thereby generating a second bank sum including a second partial accumulation of the set of waveforms, where the first and second partial accumulations of the set of waveforms are useable to generate an accumulated record of the set of waveforms.

Signal interface for a bi-directional communication device

A signal interface supports bi-directional communication in a signal communication system (36). The signal interface is preferably utilized within a cable television/communication system set top box. The signal interface includes a diplexer (76) positioned between an input/output (78) of the set top box and a signal splitter (66). By positioning the diplexer (76) before the signal splitter (66), there is no attenuation of a return data channel (RDC) signal. Thus, a lower gain RDC amplifier may be used. Additionally, the signal splitter (66) is operable over a smaller frequency range since the signal splitter (66) need only operate over the frequency bandwidth of the video signal and not the combined frequency bandwidth of the video signal and the RDC.

High speed ieee 488 bus interface system and method

Номер: WO1993024887A1

A modified IEEE 488.1 bus (104) interface (100-A, 100-B) increases, by as much as a factor of eight, the rate at which inter-instrument data transfers can be performed. The bus interface state machines (142, 144, 146, 148, 150, 160) presented in the ANSI/IEEE Std 488.1-1987 have been modified so that if all the devices (106) involved in a particular date transfer are equipped to handle high speed data transfers, then a modified data transmission methodology is used so as to enable multiline messages to be transmitted at a higher speed than would otherwise be possible. If any of the devices (106) involved in a particular data transfer does not have an interface equipped to handle high speed data transfers, this condition is automatically detected by the other interfaces with high speed capability, and then the standard data transmission methodology is used. The high speed data transmission mode is totally transparent to the controller (102, 120) software in that it does not require any changes to the controller (102, 120) software nor to the device drivers and device (106) application programs.
