CONDITIONAL ACCESS WITH TIMEOUT |
| 摘要 |
A method can include receiving a first memory load request by a conditional load with time out (CLT) device at a first time. The first memory load request can specify a first condition. A first determination of whether the first condition is satisfied is performed. The CLT device determines a wait period when the first condition is not satisfied. A reply is issued. The reply indicates that the first condition is satisfied when the first condition is satisfied. The reply indicates that the first condition is not satisfied when the duration of the wait period exceeds a time-out threshold. When the first condition is not satisfied, a first memory store request can be received during the wait period and a second determination of whether the first condition satisfied performed. The reply indicates that the first condition is satisfied when the second determination is that the first condition is satisfied. |

1. A method for responding to memory requests, comprising:
receiving a first memory load request by a conditional load with time out (CLT) device at a first time, the first memory load request specifying a first condition and a first memory address; performing a first determination of whether the first condition is satisfied; starting a timer at the CLT device to determine a wait period when the first condition is not satisfied; and responding to the first memory load request with a reply, wherein the reply indicates that the first condition is not satisfied when the duration of the wait period exceeds a time-out threshold. |
