摘要:
The present invention discloses an integrated circuit arrangement (100) comprising a data communication network comprising a plurality of connections (300), a plurality of modules (110) coupled to the data communication network via at least one network interface (120), the network interface comprising a plurality of buffers; a remote service module (150) being coupled to the data communication network via a further network interface (140), wherein each of said modules (1 10) is arranged to provide its network interface (120) with a service request (200) for the remote service module (150), said network interface being arranged to extend said service request with a first identifier (204) for establishing a network connection (300) with a remote service module (150); and a circuit portion (350) comprising a plurality of buffers (142) between the at least one network interface (120) and the remote service module (150) for storing service requests (200) from the plurality of modules (110), said circuit portion comprising decoding logic (144) for selecting one of said buffers (142) by decoding a further identifier (210) embedded in the service request (200).
摘要:
A resource controller that includes a first buffer configured to store requests of a first predefined category having a first priority. In addition, the resource controller includes at least a second buffer configured to store requests of a second predefined category having a second priority where the first priority is set such that processing requests of the first category has priority over processing the requests of the second category. Also, the resource controller includes a mechanism configured to block the requests of the first category when a predefined condition is met.

摘要:
The present application relates to a method for resource controlling comprising controlling the processing of requests of a first category having a first priority. The method comprises controlling the processing of requests of a second category having a second priority, wherein the first priority is set such that processing the requests of the first category has priority over processing the requests of the second category. The method comprises blocking requests of the first category by a mechanism that detects when a predefined condition regarding the service provided to the second category is met.
摘要:
Requests from a plurality of different agents (10) are passed to a request handler via a request concentrator. In front of the request concentrator the requests are queued in a plurality of queues (12). A first one of the agents is configured to issue a priority changing command with a defined position relative to pending requests issued by the first one of the agents (10) to the first one of the queues (12). An arbiter (16), makes successive selections selecting queues (12) from which the request concentrator (14) will pass requests to the request handler (18), based on relative priorities assigned to the queues (12). The arbiter (16) responds to the priority changing command by changing the priority of the first one of the queues (12), selectively for a duration while the pending requests up to the defined position are in the first one of the queues (12). Different queues may be provided for read and write requests from the first one of the agents. In this case, the priority raising request from the agent may be used to raise the priority level of the write queue temporarily to the level of the read queue, until all write requests issued before the priority raising command from the agent have been passed to the request handler.

摘要:
A method of determining a best-case response time of a first periodic task, the method comprising a first step based upon Rate Monotonic Analysis of determining the priorities of the tasks that have to be scheduled on a system. In order to determine whether the set of tasks can be scheduled on the system, the best-vase response time in addition to the worst-case response time is determined per task. This best-case response time is substantially equal to the difference between the start of a task with a lower priority and the completion of this low priority task, the start being right after the release of the low priority task and the completion coinciding with the simultaneous release all higher priority tasks.
