摘要： Requestors acquire tokens before issuing access requests to a memory controller. The access requests issued are accumulated in a command queue of the memory controller. When the amount of access requests accumulated in the command queue is smaller than or equal to a first threshold, or in level 0, tokens are generated at a rate equivalent to 200% of a bus bandwidth. If the amount of accumulation is greater than the first threshold and is smaller than or equal to a second threshold, i.e., in level 1, tokens are generated at a rate equivalent to the bus bandwidth. If the amount of accumulation exceeds the second threshold, the token generation is stopped.

摘要： Requestors issue access requests to a memory controller. The access requests issued are accumulated in a command queue of the memory controller. When the amount of access requests accumulated in the command queue is smaller than or equal to a threshold, a free pass (FP) is granted to specified requesters. When issuing access requests, requesters request and acquire tokens before issuing the access requests if they have no FP granted. If the requesters have an FP, they simply issue the access requests.

摘要： Processors arranged in a multi-processor configuration for substantially parallel operations receive their initialization data in order to start operations, such as graphics computations, real-time multimedia streaming, etc. Due to a change in the processing load, one or more processors might be deactivated. Subsequently, the load increases to such a level that requires all or some of the deactivated processors to be active again. In this case, the boot-up process of the entire system is not carried out as it would be time-consuming and wasteful; instead, responsive to a control signal only those processors that were previously in inactive mode are re-initialized by selecting a configuration data supplied by another processor, controller or any other intelligent programmable device. Alternatively, the configuration data may be accessed and retrieved from a local storage medium individually located in each processor, thereby re-booting only those inactive processors and without re-initializing the entire system.
