Abstract: Matrix multiply units can take advantage of input sparsity by zero gating ALUs, which saves power consumption, but compute throughput does not increase. To improve compute throughput from sparsity, processing resources in a matrix accelerator can skip computation with zero involved in input or output. If zeros in input can be skipped, the processing units can focus calculations on generating meaningful non-zero output.

Abstract: Application of a PTGDS inhibitor in preparation of a drug for treating cataracts is provided. As an effective and selective PTGDS inhibitor, AT-56 competitively inhibits production of PGD2 by occupying a catalytic site of PTGDS. The PTGDS catalyzes synthesis of the PGD2 to cause an oxidative stress injury of human lens epithelial cells, thereby promoting occurrence and development of aging and opacity of a lens. By reducing apoptosis caused by the oxidative stress injury, a degree of the cataracts can be effectively reduced.
