Embodiment Construction

[0038] The present invention will be further described below in conjunction with accompanying drawing.

[0039] The main body of the present invention is 160 multiply accumulators, which are evenly distributed in 4 basic units. Through the configuration of control words and control signals, the 160 multiplier accumulators, memory, data exchange unit and other hardware resources can work in different organizational forms, and these organizational forms determine the different working modes of the device. In addition, the present invention adopts a two-level scheduling method for hardware resource scheduling, and adopts a method of combining centralized control and distributed control in control.

[0040] The specific implementation of the present invention is divided into three levels, the first level is the device hardware architecture; the second level is the hardware organization mode; the third level is the hardware resource scheduling method. The three levels are describe...

Abstract

The present invention discloses a kind of reconfigurable digital signal processor (DSP), which has internal hardware resource capable of being reconfigured according to different application requirements so as to realize filtering operation of different forms. The present invention has the advantages of both application specific integrated circuit (ASIC) and common DSP, possesses arithmetic capacity similar to that of large scale special device, and can suit for fast Fourier transform (FFT), inverse fast Fourier transform (IFFT), FIR pulse group processing and other digital signal real-time processing fields. It has simple usage and low cost.

Description

Technical field [0001] The invention discloses a reconfigurable digital signal processor (DSP) for real-time processing of digital signals such as fast Fourier transform (FFT), fast Fourier inverse transform (IFFT), FIR pulse group processing and correlation processing. Background technique [0002] Since the 1960s, with the rapid development of computing technology and information technology, digital signal processing has developed rapidly as an independent subject and has been widely used in many fields. With the rapid development of large-scale integrated circuit technology and semiconductor technology and the continuous improvement of various real-time processing requirements, the digital signal processing capability has also increased rapidly at an exponential rate, and it has played an increasingly important role in scientific research, military and civilian fields. Important role, digital signal processing devices have become an important condition to support the rapi...
