“…Reviewed publications were micro implementations focusing on specific technical constraints like efficient retrieval methods to extract data from memory or the reuse of data to reduce the cycle time of a technical mechanism. For example one case study focused on data reuse architecture for MPEG video coding [12][13][14] [15].…”

Automation of a technical process involves the feedback of sensor data for the automated control of particular aspects of the process itself. The same feedback data can be used for other applications such as health monitoring of systems or to update a graphical user interface or to analysis process performance. In order for this data to be utilized effectively, a system architecture must be designed to provide such functionality. This architecture must accommodate the dependencies of the system and sustain the required data transmission speed to ensure stability and data integrity. Such an architecture is presented in this paper, which shows how the data needs of multiple applications are satisfied from a single source of data. Also it will show that the flexibility of this architecture enables the integration of additional data sources that can be used to protect the performance of applications that consume the data as the order of data dependencies grows.

The frame memory has long been the dominant component in a video decoder in terms of energy, area, and latency. We proposed a non-combined frame memory motion compensation (CFMMC) for video decoding which facilitates the characteristic of the perfect-matched macroblock (MB) to avoid unnecessary memory access and to save energy. The statistic result confirms that some sequences have more than 70% of MBs being perfect-matched MB. The CFMMC hardware architecture is further evaluated for latency, area, and energy. The hardware architecture shows that with SRAM-base frame memory, the equivalent gate count can be reduced by 37.7%, and the energy consumption and the latency may also be improved for sequences with enough percentage of perfect-matched MBs. Since the benefit of the CFMMC is highly dependent on the percentage of perfect-matched MBs, it is best suited for applications with large portion of static background, such as video surveillance, video telephony, and video conferencing.
