IPC: H03M1/66
Filed: 1989-12-04
Abstract: PURPOSE:To reduce the storage capacity of a necessary ROM by using plural shift registers and storage elements to attain the optimum allocation of an input signal sequence. CONSTITUTION:Shift registers can be sorted to a type having binary values in odd stages and ternary values in even stages and a type having ternary values in the odd stages and binary values in even stages. When the former type is allocated to a shift register 1a and the latter is allocated to a shift register 1b, the outputs 6a of the shift register 1a respectively become 13 bits and the outputs 6b of the shift register 1b respectively become 14 bits. Since the storage capacity of a ROM 3a becomes 8.2<13+2> = 256 kbits= 32 Kbytes and that of a ROM 3b becomes 8.2<14+2> = 512 kbits = 64 Kbytes, respective capacity can be considerably reduced.
