Abstract
The invention relates to a device for the acquisition and the processing of N asynchronous and periodic signals, such as velocity signals, N being preferably between 1 and 8, including a set of N synchronization flip-flops (B1) followed by a set of N storage flip-flops (B2) whose output is applied to a dedicated circuit via an N-input AND gate type assembly, the N synchronization flip-flops being sample by a flip-flop system (B4) from the clock of the dedicated circuit and the N automatic flip-flops (B1) being reset from said clock by an automatic flip-flop (B3).
Claims13
Device for the acquisition and the processing of N asynchronous and periodic input signals, including a set of N synchronization flip-flops (B1) receiving said input signals and followed by a set of N storage flip-flops (B2) storing occurrences of said input signals coming from said synchronization flip-flops, said set of N storage flip-flops (B2) having an output connected to a single timer input of a microprocessor via an N-input AND gate means which is used for the combined acquisition by said microprocessor of all the occurrences of the input signals, the N synchronization flip-flops being clocked from an internal clock of the microprocessor by a flip-flop (B4) and wherein the N storage flip-flops are reset from said clock by an automatic flip-flop (B3).
