Abstract:
Methods and system for reducing latency associated with a read operation in a processor memory system are provided. In one implementation, the method includes receiving an early indicator corresponding to read data from a memory, delaying the early indicator in accordance with a pre-determined delay such that the early read indicator is passed to a bus in advance of the read data; and dynamically adjusting the pre-determined delay using an adjustment delay circuit, the pre-determined delay being adjusted responsive to a change in operational speed of the bus or change in operational speed of a processor coupled to the bus.
