Problems solved by technology

Clearly, it is not desirable to embed highly complex, resource-hungry, and power-hungry devices in commodity and industrial goods, as this would adversely increase manufacturing costs for manufacturers and purchase and purchase costs for owners of such goods. ongoing cost

Embodiment Construction

[0010] now go to figure 1 , shows an example of a data flow 100 in construction and plotted against a timeline 102 . The data stream is constructed starting from a header 103, and various payload data items are added to the data stream, which may include data retrieved from storage (e.g., via direct memory access (DMA) 106 from a processor) memory retrieval or otherwise retrieved from external memory (Ext Mem) 108) static data 104. The same item may be available from more than one location, and each location may be subject to different costs and other constraints. For simplicity, only one exemplary static data item is shown; but it will be clear to those skilled in the art that most data streams will include more than a single such item. Static data 104 will typically have been stored in some storage location and will simply be retrieved as is and positioned in the data stream. Instead, the dynamic data 110 , 112 , 114 is transformed in some way in preparation for its inclu...

Abstract

A technique for operating a data source device to assemble a data stream that complies with data flow constraints, the technique including obtaining a plurality of data items by accessing and / or transforming data in memory. An accessor is selected based on an estimate of access constraints prior to completing said access to data in memory. A transformer is selected based on an estimate of transformation constraints, including any data acquisition constraints, prior to completing the transformation of the data. The access constraints and transformation constraints depend on the system state at the data source system. The data item is positioned in the data stream, and in response to achieving compliance with the data stream constraint, the data stream is transmitted.

Description

technical field [0001] The present invention relates to techniques for controlling the assembly of data streams at a data source device or component, and more particularly to the assembly of data streams for passing from a data source device or component to another data source or component, more particularly , refers to such assembly when the data to be assembled into a data stream can originate as data from memory or as data derived from a data creation or data transformation function. Background technique [0002] In the assembly of data streams from different data sources, it is well known to those skilled in the art of data processing that constraints and costs apply to various data acquisition, creation and transformation activities. Such costs and constraints may apply to the assembly of data streams as a whole, for example may be the need to make a data stream available at a specific time or within processor cycle consumption constraints. Many other such constraints ...
