RESIDUE-BASED ERROR DETECTION FOR A PROCESSOR EXECUTION UNIT THAT SUPPORTS VECTOR OPERATIONS |
摘要 |
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. Configuring a residue-generation tree to be split into multiple residue generation trees facilitates residue checking multiple independent vector instruction operands within a full width dataflow in parallel or alternatively residue checking a full width operand of a standard instruction. |
