Design and implementation of high-speed pulse acquisition module of domestic processor

The working modes of the high-speed pulse acquisition module based on the SPARC architecture domestic processor provided by the invention can be divided into three types: a counting mode, an encoder mode and a measurement mode; the counting mode can be divided into continuous counting, single counting and periodic counting, the encoder mode can be divided into an encoder X1, an encoder X2 and an encoder X4, the measurement mode can be divided into a frequency measurement mode, a rotation speed measurement mode and a periodic time measurement mode, a domestic SPARC V8 architecture processor is adopted, key components are domestic devices, autonomous controllability can be achieved, and the measurement precision is high. A pulse input signal can be switched and configured between 5V and 24V, selection can be carried out according to requirements of clients, the cost can be reduced, the usability of the high-speed pulse acquisition module can be improved, the high-speed pulse acquisition module communicating thr
