Appeal No. 1998-1507
Application No. 08/499,988
The invention is directed to converting a floating point
number to a programmable fixed point number best illustrated
by
reference to representative independent claim 1 reproduced as
follows:
1. A programmable floating point to fixed point
converter, comprising:
a shifter having a data input coupled for receiving a
signal representing a mantissa of a floating point number and
an output for providing a fixed point number;
an adder having a first input coupled for receiving an
offset signal that programs the floating point to fixed point
conversion, a second input coupled for receiving a signal
representing an exponent of said floating point number, and an
output coupled to a shift control input of said shifter for
controlling shifting of said mantissa of said floating point
number to convert to the fixed point number.
The examiner relies on the following reference:
Waggener, Jr. (Waggener) 5,161,117 Nov. 3, 1992
Claims 1 through 19 stand rejected under 35 U.S.C. § 103
as unpatentable over Waggener.
Reference is made to the brief and answer for the
respective positions of appellants and the examiner.
