Filed: 1983-03-25
Abstract: PURPOSE:To shorten the whole operation time of vector operation mechanisms by installing several series of vector operation mechanisms which generates the address of a side to be based and simultaneously executing vector operation in parallel after dividing the calculation. CONSTITUTION:A total of 2N series of vector operation mechanisms are installed. A vector data control circuit 28 discriminates DELTA=to be based/base and 1/2N and, when DELTA<=1/2N, sets an initial value in all digitized differential analyzers DDA, an address counter to be based for calculation, and a counter to be based for calculation. When the setting of the initial value is completed, each calculating mechanism operates by using each parameter in response to an operation step control clock signal. Each base address counter for calculation adds + or -2N to a calculated result and supplies the added result to the memory 29. Each DDA sums up 2NXDELTA and makes the address counter to be based for calculation cumulate the overflow value and supplies the cumulated overflow value to the memory 29. Each length counter counts the calculating frequency and controls the operation of each operation mechanism. Each memory write control circuit repeats the addition of one to the address and completes the vector drawing.

Abstract: PURPOSE:To simplify a circuit constitution by generating a same M series signal while differentiating a start position of the signal with respect to data bits 1, 0. CONSTITUTION:When a data bit 1 is given to an M series generator 30 in a memory module 12 from a memory controller 26, a load circuit 36 sets an initial value of a setting device 38 to a shift register 32 and an M series signal is generated by supplying a shift clock to an input stage of the shift register 32.
