Reconfigurable Dataflow Architecture for Multiple Activation Functions on FPGA

Runsen Ant, X. H. Xie, Hua Yuan, Y. S. Lin

This paper presents a reconfigurable accelerator that unifies seven distinct nonlinear functions into a single, flexible hardware architecture. Efficient approximation of nonlinear functions is achieved by dedicated brain floating point 16(BF16) compute units. A carefully designed parallel pipeline architecture is proposed to …

$\mathcal R(3780)$ Resonance Interpreted as the $1^3D_1$-Wave Dominant State of Charmonium from Precise Measurements of the Cross Section of $e^+e^-\rightarrow$ Hadrons

M. Ablikim, М. Н. Ачасов, P. Adlarson, X. Ai et autres

We report the precise measurements of the cross section of $e^+e^-\rightarrow$ hadrons at center-of-mass energies from 3.645 to 3.871 GeV. We thereby perform the most precise study of the cross sections and find a complex system composed of three resonances of $\mathcal …

Observation of an isoscalar resonance with exotic $J^{PC}=1^{-+}$ quantum numbers in $J/ψ\rightarrowγηη'$

M. Ablikim, М. Н. Ачасов, P. Adlarson, S. Ahmed et autres

Using a sample of (10.09$\pm$0.04)$\times$10$^{9}$ $J/ψ$ events collected with the BESIII detector operating at the BEPCII storage ring, a partial wave analysis of the decay $J/ψ\rightarrow γηη'$ is performed. The first observation of an isoscalar state with exotic quantum numbers $J^{PC}=1^{-+}$, denoted …
