Data-structure builder for VLSI/CAD software

Eum, Doo-hun 19 October 1990 (has links)
Relational database systems have successfully solved many business data processing problems. The primary reason of this success is that the relational data model provides a simple, yet flexible view of data as tables. In studying VLSI/CAD data, we noticed that they are often represented in formats similar to relational tuples. Therefore, they can be stored easily in relational tables. However, it is generally agreed that conventional relational database systems are inefficient for VLSI/CAD applications, since such applications often access large amounts of data repetitively. In order to solve this problem, we designed and implemented a data mapping subsystem that converts VLSI/CAD data stored in relational tables into internal data structures so that they can be efficiently manipulated in C. By using our data mapping language, we could reduce the amount of code required by the data-structure construction parts of some real VLSI/ CAD tools to about 1/10 of that required by C implementation. Our data-structure builder consumes several times more CPU cycles. / Graduation date: 1991

Software Design of A Soft Real-Time Communication Synthesis Method

Liao, Jian-Hong 08 September 2004 (has links)
In the era of system-on-chip, many hardware modules are embedded on a single chip. More messages communicated among on-chip modules. On-chip communication bandwidth is thus scaled up dramatically. It causes significant increase of routing area as well as relative reduction of system performance. It affects overall feasibility of a system chip. In order to solve the problem and meet the communication performance requirement of application systems. We need to consider factors that affect overall system performance and cost, communication resource allocation, message routing, and transmission control design. Thus, we proposed a soft real-time communication synthesis method. It applied the simulated annealing optimization method.. In the process, it carries out several tasks: calibration of dynamic communication cases, communication resource allocation, message routing path generation, and estimation of overall communication performance and system cost. In this research, we designed the experimental software of the communication synthesis method. We will perform experiments for its system evaluation to verify its effectiveness on system-on-chip designs.
