Abstract
The present invention is directed to a system having a shared processing resource, a plurality of processing modules and a synchronization control module. The shared processing resource is configured to perform processing operations in connection with input data provided by the processing modules, in response to a start indication. Each of the processing modules is configured to perform selected processing operations. At least one of the processing modules is configured to provide input data to the shared processing resource. Each processing module that provides input data is configured to generate a hold indication and to provide the input data to the shared processing resource in response to a synchronization barrier lock. Each processing module is configured to generate a start enable indication. Each processing module that provides input data generates a start enable indication after providing the input data. At least one of the processing modules further is configured to generate the start indication for the shared processing resource. The synchronization control module being provides, in response to each hold indication from one of the processing modules, a synchronization barrier lock for enabling one of the processing modules to provide input data to the shared processing resource.
