Abstract
Official abstract text for this publication.
A residue generating circuit for an execution unit that supports vector operations includes an operand register and a residue generator coupled to the operand register. The residue generator includes a first residue generation tree coupled to a first section of the operand register and a second residue generation tree coupled to a second section of the operand register. The first residue generation tree is configured to generate a first residue for first data included in the first section of the operand register. The second residue generation tree is configured to generate a second residue for second data included in a second section of the operand register. The first section of the operand register includes a different number of register bits than the second section of the operand register.
First claim
Opening claim text (preview).
What is claimed is: 1. A residue generating circuit for an execution unit that supports vector operations, comprising: an operand register; and a residue generator coupled to the operand register, the residue generator including: a first residue generation tree coupled to a first section of the operand register, wherein the first residue generation tree is configured to generate a first residue for first data included in the first section of the operand register; and a second…
