Abstract

The invention discloses a device for upgrading the firmware of a field programmable logic device, which comprises a microcontroller and a host connected with the microcontroller, and is characterized in that the microcontroller is connected with the field programmable logic device in a passive serial mode, after the host sends a firmware upgrading instruction, the microcontroller reads in the firmware upgrading data and configures the firmware upgrading data for the field programmable logic devices in passive serial mode. When upgrading the CPLD firmware, the device is simple to operate, and not only can eliminate the hardware problems caused by artificially welding or inserting / pulling the chip CPLD, but also can avoid the inconvenience caused by using the ISP.

Description

technical field [0001] The invention belongs to the technical field of computers, and in particular relates to a simple on-site programmable logic device (CPLD) firmware upgrade device and an upgrade method thereof. Background technique [0002] Today's society is a society where digitization and digital integrated circuits are widely used. Digital integrated circuits themselves are constantly being updated. It has developed from early tubes, transistors, small and medium-scale integrated circuits, to very large-scale integrated circuits (VLSIC, more than tens of thousands of gates), and many application-specific integrated circuits with specific functions. However, with the development of microelectronics technology, the task of designing and manufacturing integrated circuits is not completely undertaken by semiconductor manufacturers independently. System designers prefer to design application-specific integrated circuit (ASIC) chips by themselves, and hope that the ASIC...
