In one embodiment, a processing block of a block diagram receives input data including a plurality of data elements organized as a matrix of a first size. At least a portion of the input data is partitioned into a plurality of data blocks in response to user-selected parameters. A data block includes selected ones of the plurality of data elements organized as a matrix of a second size. The data processing block performs a data processing function on the plurality of data blocks in a user-specified order to yield processed data corresponding to each data block. The processed data corresponding to each data block is then reassembled to form output data corresponding to the input data and the output data is output from the processing block to another block of the block diagram.

Block processing of input data in graphical programming environments

A method is provided for extending the capability of signals in a graphical model environment. Features of a first signal type and features of a second signal type are combinable to form a combined signal type while allowing existing blocks in the graphical model environment to process the combined signal type without modification of the existing blocks. A block intended to process a signal of the first type that receives the composite signal type process the portion of the signal corresponding to the first type without regard for the second signal type portion of the combined signal. Moreover, the method allows for modification or creation of blocks that add features to a signal to form a combined signal type.

Signal inheritance in a graphical model environment

Methods and systems for performing block processing of input data in graphical programming environments are disclosed. The input data that is to be processed is partitioned into a plurality of blocks. Each block of the input data is applied to the data processing unit for processing each block of the input data. The blocks of the processed data are combined to generate output data. If the size of the output data is smaller than or equals to the size of the input data, the present invention may perform in-place block processing of the input data in which the output data is overwritten on the input data. In the in-place processing of the input data, the output data may share memory space with the input data so that the block processing saves memory space in processing the input data.
