摘要： Prefetch control logic (208) receives a cache coherence invalidation message (CCIM) indicating content to be invalidated in a cache memory (108). Upon receiving the CCIM, the prefetch control logic checks whether a prefetch trigger condition (218) is fulfilled based on information in the CCIM, and if the condition is fulfilled generates a prefetch signal. A cache controller (214) receives the prefetch signal and prefetches content from a second memory (110) to the cache memory.

摘要： A first image processing operation produces a stream of images that is used by a second image processing operation. The operations are performed by concurrently executing first and second higher level processes and first and second lower level processes. The first higher level process (20) adapts an image parameter sends calls (32) to the first lower level process (26). The first lower level process (26) is executed each time for a respective one of the images, in response to a respective one of the calls from the first higher level process (20). The second higher level process (22) sends calls to a second lower level process (28). The second lower level process (28) is executed each time for a respective one of the images, in response to a respective one of the calls from the second higher level process (22). The first lower level process (26) and the second lower level process (28) exchange each image via a buffer memory (29, 106) in a plurality of successive transactions (300) that are autonomous from the first higher level process (20) and the second higher level process (22). The first high level process (20) sends signals to the second high level process (22) each for a respective one of the images, each signal indicating (34) the image parameter for the corresponding image. The calls (37a) from the second higher level process (22) to the second lower level process (28) for each of the image are sequenced after reception of the signal for that image by the second higher level process (28).

摘要： The present invention relates to the implementation for implementing multi-tasking on a digital signal processor. For that purpose blocking functions are arranged such that they do not make use of a processor's hardware stack. Respective function calls are replaced with a piece of inline assembly code, which in stead performs a branch to the correct routine for carrying out said function. If a blocking condition of the blocking function is encountered, a task switch can be done to resume another task. Whilst the hardware stack is not used when a task switch might have to occur, mixed-up contents of the hardware stack among function calls performed by different tasks are avoided.
摘要翻译：本发明涉及在数字信号处理器上实现多任务的实现。为了这个目的，阻塞功能被布置成使得它们不使用处理器的硬件堆栈。相应的函数调用被一段内联汇编代码替换，代替执行分支到用于执行所述功能的正确例程。如果遇到阻塞功能的阻塞状态，则可以完成任务切换以恢复其他任务。虽然可能需要发生任务切换时不使用硬件堆栈，但是避免了由不同任务执行的功能调用中的硬件堆栈的混合内容。

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 and a resource controller for controlling requests to a shared electronic resource, is described. The requests are arranged in the queue together with a counter which is set to a predetermined start value, the requests are served in an order chosen to take account of the number of commands necessary to process the requests in the queue, the service of each request is performed together with a decrement or increment of the counters for all requests which have been a longer time in the queue than the request that is served, and the request, which has been in the queue for the longest time of the requests in the queue is served when the counter of the that request has reached a predetermined limit value.

摘要： An image compression unit for compressing image data (ID) having a plurality of pixels, each with one or more color samples, into a compressed format (CF) is provided. The image compression unit comprises a color lookup table generation unit (311) for generating a color lookup table having one or more colors and for transmitting the color lookup table in the compressed format (CF). The image compression unit further comprises a pixel mode determination unit (312) for determining for at least one pixel of the image data (ID) a pixel mode and for transmitting for the at least one pixel a pixel mode identifier for identifying the pixel mode in the compressed format (CF). A first pixel mode corresponds to the case that the at least one pixel matches one of the one or more colors in the color lookup table and a second pixel mode corresponds to the case that the at least one pixel does not match one of the one or more colors in the color lookup table. The image compression unit further comprises a color lookup table encoding unit (313) for encoding pixels whose pixel mode is the first pixel mode and a predictive encoding unit (314) for predictively encoding pixels whose pixel mode is the second pixel mode.
