[VHDL-FPGA-Verilog] booth_mul

Description: 一种可以完成16位有符号／无符号二进制数乘法的乘法器。该乘法器采用了改进的Booth算法，简化了部分积的符号扩展，采用Wallace树和超前进位加法器来进一步提高电路的运算速度。本乘法器可以作为嵌入式CPU内核的乘法单元，整个设计用VHDL语言实现。-a 16 to be completed with symbols/unsigned multiplication of the number of binary multipliers. The multiplier used to improve the Booth algorithm, simplified some of the plot symbols expansion Wallace tree and used-ahead adder circuit to further enhance the computing speed. The multiplier can be used as embedded CPU cores multiplication modules, the entire design with VHDL.

[Other] DesignofVeryDeepPipelinedMultipliersforFPGAs(IEEE)

Description: 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.-FPGA pipelined designs on paper This work investigates the use of very deep pipelines forimplementing circuits in FPGAs, where each pipelinestage is limited to a single FPGA logic element (LE).

[VHDL-FPGA-Verilog] multiplier

Description: 8*8乘法器及其测试：采用booth编码的乘法器：1． ultipler_quick_add_4 即4位的并行全加器，在这里主要起了两个作用：第一个是在求部分积单元时，当编码为3x时用来输出部分积；另外一个是在将部分积加起来时，求3到6位时所用到。 2． ultiplier_quick_add_5 即5位的并行全加器，这里用来分别计算积的7到11位和12到16位。 3． ultiplier_unit_4 这个模块是用来实现部分积的，每一个模块实现一个部分积的4位，因此一个部分积需要4个这个模块来实现。总共需要12个这样的模块。 4．Multiplier_full_add 这是一位的全加器，在实现部分积相加的时候，通过全加器的阵列来实现的。
