[Other resource] DesignofVeryDeepPipelinedMultipliersforFPGAs(IEEE) DL : 0: 关于FPGA流水线设计的论文 This work investigates the use of very deep pipelines for implementing circuits in FPGAs, where each pipeline stage is limited to a single FPGA logic element (LE). The architecture and VHDL design of a parameterized integer array multiplier is presented and also an IEEE 754 compliant 32-bit floating-point multiplier. We show how to write VHDL cells that implement such approach, and how the array multiplier architecture was adapted. Synthesis and simulation were performed for Altera Apex20KE devices, although the VHDL code should be portable to other devices. For this family, a 16 bit integer multiplier achieves a frequency of 266MHz, while the floating point unit reaches 235MHz, performing 235 MFLOPS in an FPGA. Additional cells are inserted to synchronize data, what imposes significant area penalties. This and other considerations to apply the technique in real designs are also addressed.

[Industry research] Vhdl-Implementation-of--Fast-32x32-Multiplier-Bas DL : 0: The Vedic mathematics is quite different from conventional method of multiplication like adder and shifter. This mathematics is mainly based on sixteen principles. The multiplier (referred henceforth as Vedic multiplier) architecture based on the URDHVA TIRYAKBHYAM (Vertically and cross wise) sutra is presented. The existing method is 16*16 bit multiplication in relatively less speed. The proposed method is 32*32 bit multiplication in terms of relatively high speed, low power, less area and less delay. This will help in designing multiplier in VHDL, as its give effective utilization of structural method of modelling. This also gives chances for modular design where smaller block can be used to design the bigger one.-The Vedic mathematics is quite different from conventional method of multiplication like adder and shifter.
