Abstract
An integrated circuit includes one or more processing units that execute instructions that employ a register file, control logic creates a pre-startup register free list, prior to normal operation of at least one of the processing units, that includes a list of registers devoid of defective registers. In some implementations, no column and row repair information is provided to register file repair logic. In certain examples, the register file is configured as a repair-less register file. During normal operation of the one or more processing units, the integrated circuit employs the pre-startup register free list to select registers in a register file for the executing instructions. Associated methods are also presented.
