Abstract

PURPOSE:To enable to realize the operation of matrix in high speed with a small unit, by splitting the matrix{xi}into upper and lower partial bits, synthesizing it with the matrix{hij}taking yi of the matrix{yi}to obtain{yi}. CONSTITUTION:The switch 17 is set to the memory 12, the upper rank 8-bit of the matrix{xi}is read out and given to the memories 18, 19 as the address signal, the partail sum of yi of the matrix{yi}, and hi of the matrix{hija}is read out from the memories 15 and 16, and they are synthesized 21. The partial sum of hi and yi in 15-bit is obtained at the addition circuit 23. Next, the swich 17 is selected to the memory 13, the lower 8-bit of xi is fed to the memories 18, 19 to read out the partial sum of yi, hi is read out from the memories 15 and 16, and the partial sum of hi and yi is added with weighting to store the lower bit of xi to the memories 18 and 19. Similarly, operation is made to x2...xN1 and h12...h1N to store them in the memories 18 and 19. y1 is obtained from the partial sum of yi. Thus, the operation of matrix can be realized with small size and in high speed.
