A control system based on fpga that can automatically expand addresses

Abstract

The invention relates to a FPGA-based control system capable of automatically extending the address. The system includes an address generation module, multiple address decoding modules and multiple address control modules. Each column corresponds to one address decoding module, and each row corresponds to one address control module. The address generation module generates one address, and the address is transmitted to each address decoding module via a first bus. The address decoding module receives the address, and then compares the received address with the address of the address decoding module to decode an address open Word Line, and finally returns a signal to the address control module. The address control module judges whether the current line has a signal or not, and transmits the signal to the address generation module via a second bus, and the address generation module resets or add 1 to a corresponding part of the address according to the signal. The control system is used for configuring data to the modules of the FPGA, the address can be extended freely and is adaptive to the FPGAs of various types. The reliability is high and the tape-out risk is low.

Description

technical field [0001] The invention belongs to the technical field of programmable logic devices, and relates to a control system, in particular to an FPGA-based control system that can automatically expand addresses. Background technique [0002] Programmable logic device FPGA, through software tools, development, simulation and testing, quickly program the design into the device, saving a lot of non-repetitive engineering costs and circuit development cycles, while programmable logic devices are based on repeated configuration storage technology , you only need to re-download the programming to complete the modification of the circuit. Programmable logic devices have the advantages of short development cycle, low cost, low risk, high integration, high flexibility, and easy maintenance and upgrade of electronic systems. Therefore, they are favored by the majority of end product users and become the mainstream of integrated circuit chips. , and are widely used in various f...

Problems solved by technology

Because it is necessary to redesign a set of corresponding address control systems for the development of FPGAs of different sizes. For FPGAs of different sizes, a set of address control systems cannot be shared. Because each design of a set of address control systems requires labor costs, and new development There will be certain risks in the address control system
