Patent Searching and Data


Title:
DIGITAL FILTER INTEGRATED CIRCUIT DEVICE
Document Type and Number:
Japanese Patent JPS6165616
Kind Code:
A
Abstract:

PURPOSE: To execute efficiently circuit integration by providing a means for writing data from at least an operation data input terminal to a storage circuit and an expanding means in the filter order direction.

CONSTITUTION: The titled device consists of a storage circuit 4, adders 51, 52, registers 61, 62 storing intermediate data, control gates 81, 82, a signal input terminal 1, intermediate operation data input/output terminals 21, 31, an internal data bus (22→81→32), its input/output terminals 22, 32 and a signal input terminal 7 for write signal taking the timing to write the data in the storage circuit. In programming a filter coefficient, the control gate 81 is set and the control gate 82 is reset, write data is inputted from the 22 to the storage circuit 4 to write it in the timing of a write signal input 7.
