A dedicated processing module includes an input for data to be processed and an output for processed data. A block input and a block output are also included. A processing component for the module performs a digital processing operation on the data present at the data input and applies the processed data at the data output. The processor may further generate a block request. A control device within the module reproduces, at the block output, a block request applied to the block input or generated by the processing component. The control device thus may operate to block the application of processed data at the data output upon receipt of a block request at the block input. Two or more dedicated processing modules may be connected in series with each other to form a processing flow chain with the data output of one module connected to the data input of a subsequent module. Additionally, the block output of the subsequent module is connected to the block input of the preceding module.
