Abstract:
1. A semiconductor integrated circuit device having a plurality of processing elements and a communication circuit interconnecting said processing elements, wherein: said communication circuit comprises a latch circuit having a direct connecting mode to directly connect a first ALU in a first processing element to a second ALU in an arbitrary second processing element through said latch circuit of said communication circuit, so that said first and second ALU's constitute a combinational logic circuit, an output of said combinational logic circuit being a function of a current input only, with data from said input to said output passing through only non-clocked components; a plurality of said processing elements are coupled together as a block forming a processing element group functioning as a single processing circuit operating with a clock signal; wherein each of said processing elements comprises a connection control circuit controlling a connection to a neighboring processing element and selecting a neighbor communication input source from: wherein said processing element group carries out a multi-bit operation or an accumulating operation by propagating data to said processing elements in said processing element group by a single pulse of said clock signal.
