Abstract
A process and associated apparatus for performing bit pattern detection, such as leading one detection and leading transition detection for early normalization of the result of an operation on floating point numbers. Such an operation can be an addition or a subtraction of floating point numbers. In parallel with this operation, this process and associated apparatus divide the operands into bit groups. These bit groups are operated on and represented by states and addresses, which are propagated through several levels to detect the bit pattern.
