Low-complexity 1-bit signal decoder and design method thereof

Abstract

The invention discloses a low-complexity 1-bit signal decoder and a design method thereof. The decoder comprises a counter module, a fixed subtraction module, M decoder sub-modules and an output control signal generation module; the counter module inputs a reset signal and a clock signal, the M decoder sub-modules form a parallel operation processing unit, the M-1 fixed subtraction modules are arranged between the counter module and the decoder sub-modules in a one-to-one correspondence manner, and the address numerical value difference of the adjacent decoder sub-modules is L; data inputs ofthe M decoder sub-modules are all 1-bit digital signal streams, enabling ends of the M decoder sub-modules are all connected with the output control signal generation module, and the M decoder sub-modules output N-bit digital signal streams. The invention further provides a design method of the low-complexity 1-bit signal decoder. The invention has extremely low complexity and power consumption, is suitable for processing high-speed data, can be realized in the form of an integrated circuit, and is suitable for high-bandwidth signal processing.

Description

Technical field[0001]The invention belongs to the field of signal processing, and specifically relates to a low-complexity 1-bit signal decoder and a design method thereof.Background technique[0002]Digital signal processing technology has become more and more popular and has brought unprecedented progress in many fields. The development of electronic information technology and integrated circuit technology has made it necessary to convert analog signals into digital signals in more and more fields for further use of digital The signal processing method performs specific processing. The 1-bit digital stream level signal is a method of transmitting low-speed analog signals or low-speed multi-bit digital signals by means of high-speed 1-bit logic level transitions. The aforementioned 1-bit digital stream level signal may be pulse density modulation (PDM) or pulse width modulation (PWM), but is not limited to the above two signal modulation forms. The converted multi-bit digital signal ...
