Decoupling capacitors have been mostly used to reduce the power/ground bounce of high-speed digital systems and boards. In this paper, we present a more powerful circuit model for power and ground bounce. This circuit reduces the power and ground bounce by the way of suppressing voltage increase through the resistance which varies with power fluctuation. We present numerical analysis and simulation data by comparing decoupling capacitors.","PeriodicalId":346808,"journal":{"name":"AP-ASIC'99. First IEEE Asia Pacific Conference on ASICs (Cat.

To quickly collect and register IP from companies and universities, we have to give some benefits to the IP providers while minimizing the IP standard they must observe. To provide IP suitable for IP users, we have to have an IP DB which contains rated IP and has sufficient and convenient functions such as IP search, compare and download. Finally, to satisfy the various requirements of both IP providers and IP users, we have to have many business models and license models working in reality. We present KETI's works to solve these problems, focusing on the development and management of an IP DB.","PeriodicalId":346808,"journal":{"name":"AP-ASIC'99.

A scheduling algorithm for pipelined data path synthesis with gradual mobility reduction 一种逐步降低迁移率的流水线数据路径综合调度算法

The algorithm first checks the possibility of scheduling in the case of being assigned to the earliest step or to the latest step among the assignable control steps of all operations. If it is impossible to assign an operation to those steps due to resource constraint violation, the algorithm does away with those steps, that is, reduces the mobility of the operation. The scheduling algorithm is iterated until final schedule is obtained. If the final schedule is not obtained, even though there is no operation to reduce a mobility, we select a proper operation to reduce the mobility using the current scheduling state that is represented by parameters. A 16 point FIR filter and 5th order elliptic wavefilter are used to illustrate the scheduling algorithm.","PeriodicalId":346808,"journal":{"name":"AP-ASIC'99.

A family of designs is identified in which this technique is applied to different bit slices of the matrix data and the optimal design within the family is determined using transition activity analysis driven by real image sequences. Our results suggest that the optimal design using MSB-controlled inversion coding yields power savings of 33% for DCT data and 46% for IDCT data. These results are remarkable since existing bus-invert coding techniques have high overheads and are only effective for system-level high-capacitive buses.","PeriodicalId":346808,"journal":{"name":"AP-ASIC'99.
