FPGA-Based CNN Inference Accelerator Synthesized from Multi-Threaded C Software

A deep-learning inference accelerator is synthesized from a C-language software program parallelized with Pthreads. The software implementation uses the well-known producer/consumer model with parallel threads interconnected by FIFO queues. The LegUp high-level synthesis (HLS) tool synthesizes threads into parallel FPGA hardware, translating software parallelism into spatial parallelism. A complete system is generated where convolution, pooling and padding are realized in the synthesized accelerator, with remaining tasks executing on an embedded ARM processor. The accelerator incorporates reduced precision, and a novel approach for zero-weight-skipping in convolution. On a mid-sized Intel Arria 10 SoC FPGA, peak performance on VGG-16 is 138 effective GOPS

Ceraclea of the People\u27s Republic of China (Trichoptera: Leptoceridae)

The species of the long-horned caddisfly genus Ceraclea for the People\u27s Republic of China are reviewed for the first time since 1975. Twenty-nine species of Ceraclea are known from China and are described or redescribed in the subgenera Ceraclea and Athripsodina, with 4 of them new to science

Setodini of the People\u27s Republic of China (Trichoptera: Leptoceridae, Leptocerinae)

The Chinese species of the long-horned caddisly tribe Setodini are reviewed, based on the recent revision by Schmid. Twenty-two species of Setodini are reported from China, including six species previously described in the paraphyletic Setodes and one in monophyletic Trichosetodes, twelve species being described as new to science in Setodes and one Trichosetodes, and two unnamed species of Setodes whose females are described

Activation of the p21-activated protein kinases from neutrophils with an antibody that reacts with the N-terminal region of Pak 1

AbstractNeutrophils contain two renaturable p21-activated protein kinases (Paks) with molecular masses of ca. 69 and 63 kDa that undergo rapid activation upon stimulation of these cells with the chemoattractant fMet-Leu-Phe. We now report that these kinases undergo a massive, ATP-dependent activation in lysates of unstimulated neutrophils during immunoprecipitation with an antibody generated to residues 2–21 of the N-terminal region of Pak1. This activation was specific as it was completely blocked by a peptide that corresponds to residues 2–21 of Pak1 and was not observed with an antibody generated to the C-terminal region of Pak 1. The properties of the Paks activated with the antibody were virtually identical to those observed for these kinases from stimulated neutrophils, or activated in vitro with Rac-GTPγS plus ATP. These data indicate that perturbation of the N-terminal region of Pak can trigger activation of this enzyme, and that both the 69 and 63 kDa kinases may represent forms of Pak 1 that differ in their content of phosphate.©1997 Federation of European Biochemical Societies

Chiral Rings and Physical States in c<1 String Theory

We show how the double cohomology of the String and Felder BRST charges naturally leads to the ring structure of $c<1$ strings. The chiral ring is a ring of polynomials in two variables modulo an equivalence relation of the form $x^p \simeq y^{p+1}$ for the (p+1,p) model. We also study the states corresponding to the edges of the conformal grid whose inclusion is crucial for the closure of the ring. We introduce candidate operators that correspond to the observables of the matrix models. Their existence is motivated by the relation of one of the screening operators of the minimal model to the zero momentum dilaton.Comment: 20 pages, harvmac, 4 figures (drawn using LaTeX appended to the end of the file), IMSc--92/3
