Abstract
The register file of a processor includes embedded operand queues. The configuration of the register file into registers and operand queues is defined dynamically by a computer program. The programmer determines the trade-off between the number and size of the operand queue(s) versus the number of registers used for the program. The programmer partitions a portion of the registers into one or more operand queues. A given queue occupies a consecutive set of registers, although multiple queues need not occupy consecutive registers. An additional address bit is included to distinguish operand queue addresses from register addresses. Queue state logic tracks status information for each queue, including a header pointer, tail pointer, start address, end address and number of vacancies value. The program sets the locations and depth of a given operand queue within the register file.
