A new recoding truth-table (using redundant signed-digit numbers) with a symmetrical complemented relationship between input minterms and their corresponding output bits is developed. Multi-bit parallel digital circuits for both the recoding algorithm and the adder logical functions are realized using ...
Adder unit 468, which can have the same structure as adder unit 460, is at the highest level of the tree, and its output is provided on a count line connected to other components, such as to a shift register. All of the adder units in the tree are clocked to obtain each bit of ...

Both the Full Adder (602) and/or the output stage Latch (603) can be bypassed, and the LUT output can directly drive the final output stage (605), which is feeding the Internal Fabric. One can conclude that Logic Units can be daisy-chained, since the inputs are fed from the Fabric ...
In this configuration therefore, the "transition event" is the output carry bit indicating overflow of the most significant bit of the adder. The method described above, hereinafter referred to as "single incremental interpolation", has the advantage of maintaining the correct relative positioning ...
It can also be verified, e.g., by a truth table, that the simplified adder circuit 166, of the smaller shaded area of FIG. 16a, correctly implements arithmetic Equation M2. So borrow parallel counter 5_1 circuit implements the equation system. It is easy to see that borrow parallel ...
In the past, this process has been performed in a sequential fashion using chains of carry/borrow adder stages or the like. Alternatively, magnitude comparisons may be performed in parallel using a plurality of Manchester carry chains 300. A Manchester carry chain 300 is shown generally in FIG....
Thus, we can simplify the logic function of the 1-bit full adder, 4-bit adder, and 4-2 compressor so that we can further reduce the critical path delay and the number of transistors. For example, the truth table of simplified full adder is given in Table 3. Table 3. Truth table of...
