ABSTRACT:
A floating point processing system and method of operation are disclosed. Single word precision denormalized operands and also misaligned operands are detected while such operands are being loaded into the first stage of a pipelined floating point unit. Such operands are aligned to a double word boundary and/or single word operands are normalized by a processing stages inserted into the pipe ahead of the first stage of the pipelined floating point unit thereby entering a one stage delay. In this way, misaligned operands and single word denormalized operands can be processed without the need for example to cancel the instruction, execute a normalize or alignment instruction and then re-launch the original instruction.
