Special-Purpose Computer Organization for Double-Precision Realization of Digital Filters
J. Robert Heath, C. C. Carroll · IEEE Transactions on Computers · 1970
This paper concerns the design, implementation, and testing of a stored-programmed special-purpose computer that, when employed as a digital filter, satisfies the requirement of reduced deadband for the input interface element (the analog-to-digital converter). This is accomplished by using a double precision arithmetic process which employs shorter word lengths; and consequently, the physical size (component-wise) and the calculation time of the filter are reduced.
