In this work, we address the design of an adder in Tunable Floating-Point (TFP) precision. TFP is a variable precision format in which a given precision can be chosen for a single operation by selecting a specific number of bits for significand and exponent in the floating-point representation. By tuning the precision of an algorithm to the minimum precision achieving an acceptable target error, we can make the computation more power efficient. In previous work, we introduced a unit for TFP multiplication. Here, we focus on floating-point addition.
