Abstract

The invention provides a method capable of accelerating configuration based on an FPGA (Field Programmable Gate Array). The method comprises the following steps: configuring configuration data of unused resources and configuring configuration data of resources which are actually used, so as to effectively shorten configuration time and reducing the capacity of a configuration code. The invention further provides a corresponding control system capable of accelerating the configuration based on the FPGA according to the method; the control system comprises a control module, a data displacement module and an address analysis module; and the control system can accelerate a configuration speed, a configuration data capacity is reduced and a storage space is saved.

Description

technical field [0001] The invention belongs to the technical field of programmable logic devices, in particular to an FPGA-based accelerated configuration method and control system. Background technique [0002] Programmable logic devices, through software tools, development, simulation and testing, generate configuration codes, quickly program configuration codes into devices, save a lot of non-repetitive engineering costs and circuit development cycles, and programmable logic devices are based on repetitive The configuration storage technology only needs to re-download the configuration code 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...
