This second arrangement reduces the system latency because, rather than waiting for a processor to access shared data, the data can be accessed on a shared basis. Instead, the processors have to perform a number of read and write operations to access the shared data. The shared data is accessible to multiple processors but cannot be directly accessed by the processors. Second, a bank of registers can be dedicated to holding shared data. Each processor has its own private copy of the data stored in the CM. First, a central memory (CM) can be dedicated to storing data that is required by multiple processors. There are three types of data sharing that are often implemented in multi-processor systems. Sharing data across processors can greatly accelerate the performance of a multi-processor system since, rather than requiring a single processor to access the data to perform its task, the data can be shared with the multiple processors. Accordingly, any attempt to provide improved performance by increasing the number of processors must be accompanied by a careful system design in order to avoid disabling resources that are not fully occupied.Īnother problem with existing multi-processor systems is that, since processing tasks are typically executed in an undetermined order, it is difficult to place data in a location from which it is accessible by multiple processors. First, processors and system controllers are not always dedicated to a given task, but instead their processing resources are shared with a variety of tasks and interrupt sources. While providing a distinct advantage in performance, these systems have a number of problems. Multi-processor systems are currently being used in a variety of applications to accelerate processing functions. The present invention relates to digital systems, and more specifically, to the use of multiprocessor systems for accessing and sharing data. Instead of asking you, I fixed the problem by removing the power connector and resetting the car. I was helping a buddy of mine and had the same problem. This is what the problem should look like:
