[Other] 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.-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).

[Other] Component-Pruning-in-Gaussian DL : 0: 针对概率假设密度 (Probability hypothesis density, PHD) 高斯混合实现算法中的分量删减问题, 提出了基于 Dirichlet 分布的分量删减算法以改进概率假设密度高斯混合实现算法的性能. 算法采用极大后验准则估计混合参数, 采用仅依赖于混合权重的负指数 Dirichlet 分布作为混合参数的先验分布, 利用拉格朗日乘子推导了混合权重的更新公式. 算法利用负指数 Dirichlet 分布的不稳定性, 在极大后验迭代过程中驱使与目标强度不相关的分量消亡. 该不稳定性还能够解决多个相近分量共同描述一个强度峰值的问题-As far as component pruning in Gaussian mixture (GM) implementation of probability hypothesis density (PHD) is concerned, a component pruning algorithm based on Dirichlet distribution is proposed to improve the performance of Gaussian mixture implementation of probability hypothesis density. The maximum a posterior criterion is adopted for estimation of mixing parameters. Dirichlet distribution with negative exponent parameters, which only depends on mixing weights, is adopted as the prior distribution of mixing parameters. The update formulation of mixing weight is derived by Lagrange multiplier. The instability of Dirichlet distribution with negative exponent parameters is applied to driving the components irrelevant with target intensity to extinction during the maximum a posterior iteration. Besides, the problem that one peak of intensity is presented by several proximate mixing component
