A well-defined computational model allows the synchronization and activation of concurrent processes. The design environment includes the refinement steps from scheduling with dynamic processes via simplified scheduling/execution methods to the complete implementation. The relationship between specified behavioral classes and implemented states in the final core programs is the key issue in this development flow. Time uncritical parts are implemented in a heterogeneous environment communicating via a standard communication protocol. On the other hand, time critical processes and process connections can be implemented in C/sup ++/ using SystemC, thus forming core programs encapsulated in a shell to fit the introduced and implemented activation rules. An example from the world of digital image processing systems illustrates the approach.","PeriodicalId":300014,"journal":{"name":"Proceedings IEEE Computer Society Workshop on VLSI 2000.

What will be the biggest challenges facing them at that time? Then too, where are the biggest opportunities for research impact right now? To help us think about such questions, we'll look back 25 years and reflect on some lessons from the early VLSI adventures of the late 70's. We'll see how separate disciplines were merged to create a new, simplified design methodology. We'll see how QTA implementation provided students and researchers with means to rapidly explore new design spaces opened by these methods. And we'll look at how a unique university/industry/government collaboration supported and motivated all these explorations. Looking ahead, we'll speculate about whether we might be at a similar \"break-point\" in complexity and system design challenges, and about the possibility that new innovations in system design could re-revolutionize microelectronics.","PeriodicalId":300014,"journal":{"name":"Proceedings IEEE Computer Society Workshop on VLSI 2000.

The new level of complexity driven by core-based system-chips demands that designers alter the way they approach chip development in order to keep up with diminishing time-to-market requirements and stay within budgets. Embedded test enables the production of higher-quality devices in less time. The use of embedded test raises margins and significantly reduces the time required for system verification, test and debug. This paper addresses discusses embedded test technology and analyzes its impact on time-to-market, product quality and cost.","PeriodicalId":300014,"journal":{"name":"Proceedings IEEE Computer Society Workshop on VLSI 2000.

Low power VLSI architecture for 2D-mesh video object motion tracking 二维网格视频目标运动跟踪的低功耗VLSI架构

{"title":"Low power VLSI architecture for 2D-mesh video object motion tracking","authors":"Wael Badawy, M. Bayoumi","doi":"10.1109/IWV.2000.844532","DOIUrl":"https://doi.org/10.1109/IWV.2000.844532","url":null,"abstract":"This paper presents a low power VLSI architecture for video object motion tracking. Power has been reduced at both algorithmic and arithmetic levels. The video object is modeled as a 2D hierarchical structured mesh, where the deformation of the mesh represents the dynamics of the object across the video sequence. The algorithm benefits from the small number of bits that describe the mesh topology. Low power has been achieved in the algorithm level by: (1) modeling the mesh into independent triangular patches that can be processed in parallel, (2) each patch is hierarchical triangulated using structured technique, which can be pipelined using simple unit, and (3) using the three steps motion estimation algorithm to simplify the motion estimation of the mesh nodes. On the arithmetic level, low power has been achieved by using multiplication-free affine transformation because of the followed triangle topology. A VLSI architecture is developed based on the proposed algorithm. The architecture consists of two main parts, a mesh-based motion estimation unit and a mesh-based motion compensation unit. The first unit is based on parallel block matching motion estimation to optimize the latency. The second uses parallel threads. Each thread implements a pipelined chain of scalable multiplication-free affine units. The architecture has been prototyped and its performance measures have been evaluated. This processor can be used in online object-based video applications such as in MPEG-4, and VRML.","PeriodicalId":300014,"journal":{"name":"Proceedings IEEE Computer Society Workshop on VLSI 2000.

Static timing analysis identifies critical nets and critical primary input/output paths. Net clustering (based shared macro-cells and criticality) yields clusters wherein each cluster has strongly interdependent nets. Clusters and nets within every cluster are prioritized based on number of critical nets, number of nets, and the total macro-cell area. We propose two approaches to generate layouts at RTL: constructive (cluster growth) approach and iterative improvement based (simulated annealing) approach. For datapaths implemented in 0.35 /spl mu/m technology, for both approaches, we achieved an average decrease of 54% in longest wirelength and 53% in overall wirelength.","PeriodicalId":300014,"journal":{"name":"Proceedings IEEE Computer Society Workshop on VLSI 2000.

The first four delay elements that we analyze are already in general use; they are the transmission gate, cascaded inverters, thyristor, and voltage-controlled delay element. The fifth delay element, a transmission gate with Schmitt trigger, is a new architecture that we are proposing in this paper. We compare these delay elements, both analytically and through simulations, in terms of four important parameters: delay, signal integrity, power consumption, and area, and find that they have widely varying characteristics. Depending upon the delay value required in an application, results presented in this paper will enable a designer to select the most appropriate delay element that meets signal integrity, power consumption, and area specifications.","PeriodicalId":300014,"journal":{"name":"Proceedings IEEE Computer Society Workshop on VLSI 2000.

The system is composed of two parts: the controller and the motors of the robot arm. The design starts with a multilanguage system-level specification. SDL was used for the description of the controller and Matlab was used for the description of the physical behavior of the motors. The multilanguage design flow includes the refinement of the modules and the refinement of the communication between these modules described in different languages. In order to validate the overall system through the design steps, cosimulation is performed at different levels of abstraction. This experiment shows that system level model may provide an early mock-up of the design before refining the intermodule communication.","PeriodicalId":300014,"journal":{"name":"Proceedings IEEE Computer Society Workshop on VLSI 2000.
