Abstract: A digital compute-in-memory (DCIM) macro includes a memory cell array and an arithmetic logic unit (ALU). The memory cell array stores weight data of a neural network. The ALU receives parallel bits of a same input channel in an activation input, and generates a convolution computation output of the parallel bits and target weight data in the memory cell array.

Abstract: A digital compute-in-memory (DCIM) system includes a first DCIM macro. The first DCIM macro includes a first memory cell array and a first arithmetic logic unit (ALU). The first memory cell array has N rows that are configured to store weight data of a neural network in a single weight data download session, wherein N is a positive integer not smaller than two. The first ALU is configured to receive a first activation input, and perform convolution operations upon the first activation input and a single row of weight data selected from the N rows of the first memory cell array to generate first convolution outputs.

Abstract: An airsoft gun magazine allowing smooth, convenient, and efficient way to continuous drive the ratchet for fast delivering multiple projectiles including ball and paintball bullets one after another is comprised of an outer case containing an integrated magazine casings, and ratchet, dialer, coil spring, active gear, passive gear and deflection gear below the magazine casing; an inlet on top of the magazine casing and a guide channel extending up to its top; the revolving ratchet delivering torque energy to be stored in the coil spring to drive the dialer; an insertion hole disposed externally to the center of the ratchet and being incorporated to the magazine casing and exposed out of the outer case; and a key placed into the insertion hole to continuously drive the ratchet to revolve.
