PURPOSE: To improve a processing speed by providing an arithmetic and logic circuit in an on-site programmable digital signal processing integrated circuit and storing logic equivalent to a desired analog circuit element in it. CONSTITUTION: This on-site programmable digital signal processing integrated circuit 10 formed by CMOS for instance inside a semiconductor die is provided with the arithmetic and logic circuits (ALUs) 12-1-9 and D/A converters 14-1-2 and A/D converters 16-1-2 , etc., receive off-chip analog input/output signals through an I/C block 18. Mutual connection elements 22 and 24, etc., for mutually connecting respective circuit blocks are arranged and they are provided with an anti-fuse and a path transistor, etc., and enable a mutual connection program by a user. The logic of the respective ALUs is respectively equivalent to the specified analog circuit element and thus, Von-Neumann limitation is evaded. |
