bit field

(data)
Part of an item of data, storage location or message, identified as a certain number of contiguous bits starting at a certain bit position within the data. Bit position zero is usually the least significant bit.

For example, in an ARM machine code instruction the four-bit field at bits 28 to 31 (the four most significant bits in the 32-bit word) is the "condition code".

Modified flagged prefix adder can able to produce different results according generated flag bits.
This paper introduces the idea of producing flag bits to select the corresponding resultant sum and its increment and decrement results, thereby eliminating the need of special adder for third operand addition.
