Embodiment Construction

[0021] The structure shown in Fig. 1, Fig. 2, Fig. 3, and Fig. 4 is actually a specific implementation example of the present invention. Because the present invention mainly meets the application needs in the fields of computer, communication, and image, sound processing and measurement and control systems, the input and output signals in this type of system are all analog signals. As shown in Figure 1, FPMA accepts the input analog signal to the analog array, and generates digital signals in the digital array according to actual needs. The digital signals are controlled through the external MCU and human-computer interaction interface, and the final output signal still passes through the FPMA. Send out. The interface of the digital and analog parts is shown in Figure 2. Through the 1.5-bit precision high-speed analog-to-digital / digital-to-analog converter ADC / DAC and direction selector, the analog and digital signals achieve mutual communication.

Abstract

The invention relates to the field of electronic circuit design, specifically a programmable digital-analog mixing apparatus (FPMA) arrangement, which comprises a programmable digital array, a programmable analog array, an A / D and D / A converter, a programmable digital-analog I / O interface through circuit connection, wherein the number of the digital array logic units is nxm (2<=m, n<=100), the number of the disposable analog units for the analog array is k (4<=k<=50), the digital-analog conversion interface consists of the AD / DA converter and direction selector that can be arranged in each analog unit.

Description

Technical field [0001] The invention belongs to the technical field of electronic circuit design, and specifically relates to a programmable digital-analog hybrid device structure, which is suitable for application requirements in aspects such as automatic control, data acquisition, and real-time control. Background technique [0002] FPMA (Field Programmable Digital-Analog Mixed Array) is a device that can be programmed to have both analog and digital functions. It not only overcomes the shortcomings of FPGA and FPAA, but also realizes the complementary advantages of the two, making it more powerful and applicable. Generally speaking, most systems are analog / digital hybrid systems. For measurement control systems such as pressure, temperature, speed, etc., the front-end analog signal quantity must be amplified and filtered before digital processing or control can be carried out. Similarly, in signal processing systems such as communication, image, and sound, digital processing c...
