Embedded multi-functional preprocessing input data buffer in radar system
First Claim
1. An embedded multi-functional preprocessing input data buffer in radar system for receiving data and outputting the data to a module output data bus, the embedded multi-functional preprocessing input data buffer in radar system comprising:
- a clutter lock loop and multiplication circuit, selectively executing an coefficient multiplication or a clutter lock loop operation for the received data according to a working mode of a radar system;
a mode selective multiplexer coupled to the clutter lock loop and multiplication circuit for receiving the data and selectively outputting data of the clutter lock loop operation;
a dual-port memory coupled to the mode selective multiplexer for receiving and temporarily registering the data processed; and
an output multiplexer coupled to the dual-port memory, the output multiplexer comprising a plurality of output channels, selectively outputting the data temporarily registered in the dual-port memory via one of the output channels according to the working mode of the radar system.

Abstract
An embedded multi-functional preprocessing input data buffer comprises a clutter lock loop circuit, a multiplier, a mode selective multiplexer, a dual-port memory, an input multiplexer, self-testing circuit, decode circuit and an output multiplexer. The clutter lock loop and multiplication circuit selectively executes a coefficient multiplication or a clutter lock loop operation for the received data according to a working mode of the radar system. After receiving the data, the mode selective multiplexer may selectively output data processed by the clutter lock loop and multiplication circuit. The dual-port memory is coupled to the mode selective multiplexer for receiving and temporarily registering the data processed. The output multiplexer selectively outputs the data temporarily stored in the dual-port memory via a number of the output channels according to the working mode of the radar system.
