Abstract: A processing element array includes N processing elements (PE) arranged linearly, N?2, and an operating method of the PE array includes: performing a first data transmission procedure, where an initial value of I is 1 and the first data transmission procedure includes: operating, by an ith PE, according to a first datum stored in itself, and sending the first datum to other PEs for their operations, adding 1 to I when I<N, and performing the first data transmission procedure again, performing a second data transmission procedure when I is equal to N, which includes: operating, by the Jth PE, according to a second datum stored in itself, and sending the second datum to other PEs for their operations, reducing J by 1 when J>1 and the (J?1)th PE has the second datum, and performing the second data transmission procedure again.

Abstract: A faucet valve includes a housing fluidically communicated with a cold water source, a hot water source, and a discharge pipe; and an actuating handle rotatably or reciprocatively mounted in the housing, wherein a lowest buffering disk is secured under the handle and reciprocatively moving within a through hole formed in a bottom valve seat to buffer any high pressure exerting at the discharge water stream for the smooth operation of the handle.
