Online updating device for configuration files of programmable logic device

Abstract

The invention discloses an online updating device for configuration files of a programmable logic device. In an upper computer, a program package module extracts and updates the configuration files and converts the updated configuration files into standard test and programming language (STAPL) standard input files required by a Jam STAPL Byte-Code Player analysis program. A data transmitting module converts the STAPL standard input files into internet signals and transmits the internet signals to cables, and then a data receiving buffer module receives jbc files from the cables, verifies the files and preserves the files in a program storage. A program analysis module extracts configuration information of the programmable logic device from the jbc files in a data storage, the configuration information of the programmable logic device can be converted into joint test action group (JTAG) data stream through the Jam STAPL Byte-Code Player program in the program analysis module and transmits the JTAG data stream to a general purpose input / output (GPIO) simulation JTAG module. A GPIO of a microprocessor is used as a standard JTAG interface, configuration time sequence of a standard JTAG is simulated through a driving program, only four GPIOs of the microprocessor are used, and a hardware circuit is very simple. Compared with a traditional configuration method of the programmable logic device, cost is reduced greatly.

Description

technical field [0001] The invention belongs to the technical field of updating configuration files, and more specifically relates to an online updating device for configuration files of programmable logic devices. Background technique [0002] There are two main types of programmable logic devices: field programmable gate array (FPGA) and complex programmable logic device (CPLD), which are large in scale and complex in structure, and belong to the scope of large-scale integrated circuits. And self-constructed digital integrated circuits with logic functions. [0003] The traditional configuration method of programmable logic devices is generally to use integrated development software to generate corresponding target files, and complete the target chip through a dedicated download cable, that is, the programming of programmable logic devices. Usually, this configuration method requires the support of special configuration plug-ins and development software, and the configura...
