Multifunctional special multiplier for hardware in FPGA and FPGA chip

Abstract

The invention relates to a multifunctional special multiplier for hardware in an FPGA. In the multiplier, the input end of a front adder receives first serial and parallel data of the FPGA chip, and the output end of the front adder is connected with the input end of a multiplication computation unit; the output end of the multiplication computation unit is connected with the first input end of a back adder; the input end of a data selector receives the first serial and parallel data of the FPGA chip, and the output end of the data selector is connected with the second input end of the back adder; the input end of a carry controller receives the first serial and parallel data of the FPGA chip, and the output end of the carry controller is connected with the third input end of the back adder; one output end of the back adder outputs second serial and parallel data, and the other output end of the back adder is connected with one input end of a data matching comparator; and the other input end of the data matching comparator receives the first serial and parallel data of the FPGA chip. According to the multiplier, high-speed and high-performance multiplication operation can be realized; filter design and data comparison are realized; and especially the functions of multiplication and comparison of large-bit-width data are realized.

Description

technical field [0001] The invention relates to the technical field of integrated circuit design in the field of microelectronics, in particular to a multifunctional hardware-specific multiplier in an FPGA and an FPGA chip. Background technique [0002] FPGA is a logic device with abundant hardware resources, powerful parallel processing capability and flexible reconfigurable capability. These features make FPGA more and more widely used in data processing, communication, network and many other fields. [0003] Currently, in Field Programmable Gate Array (Field Programmable Gate Array, FPGA) applications, integrated circuits are required to have a programmable or configurable interconnection network, and logic gates are connected to each other through the configurable interconnection network. FPGAs, functioning as stand-alone chips or as a core part of a system, have been widely used in a large number of microelectronic devices. The definition of FPGA logic gates in a broa...
