Field-programmable gate array and transmission method for synchronizing signals between modules thereof

Abstract

The invention provides a field-programmable gate array (FPGA) and a transmission method for synchronizing signals between modules thereof. The method comprises the steps of initializing the FPGA; whena first module receives a clock pulse, detecting whether a preset event occurs; if yes, performing negation operation on a first signal output by the first module; judging whether a third signal output by a XOR gate circuit is 1; if yes, enabling a second module to execute corresponding operation and performing the negation operation on an output second signal when the next clock pulse comes; viathe XOR gate circuit, changing an output third signal to 0 according to the input first signal and second signal, and enabling the second module to enter a waiting state according to the received third signal which is 0. According to the technical scheme provided by the invention, the signals can be effectively transmitted between the different synchronous modules in the FPGA, and the more flexible function design is achieved.

Description

technical field [0001] The invention relates to the communication field, in particular to a field programmable gate array and a method for transmitting synchronous signals between modules thereof. Background technique [0002] FPGA is Field Programmable Gate Array, which is a product of further development on the basis of programmable devices such as PAL, GAL, and CPLD. It emerged as a semi-custom circuit in the field of application-specific integrated circuits (ASIC), which not only solves the shortcomings of custom circuits, but also overcomes the shortcomings of the limited number of original programmable device gates. [0003] With the development of science and technology, FPGA has been widely used in important occasions such as industry, communication, radar, and data processing. FPGA development generally uses hardware description languages ​​(such as VHDL, Verilog), so that developers do not need to use registers, connection lines and other FPGA underlying primitive...
