In this study, to deal with mixed uni- and multicast traffic, we propose an efficient buffered crossbar switching architecture called MQ-SCPX switch. Based on a guess to the load share percentage of the mixed uni- and multicast traffic, the need of buffering resource for unicast traffic might be lower, while the multicast traffic becomes more. The MQ-SCPX switch is separated into one unicast section...
This paper presents a floating-point fused multiply-add (FMA) unit with low-cost and low power techniques. To improve the performance, two single-precision operations can be performed concurrently with one double-precision datapath, which is very useful in multimedia and even scientific applications. Moreover, to reduce the additional area costs for supporting two single-precision operations in parallel,...
SMS4 is a 128-bit block cipher used in the WAPI standard for protecting data packets in WLAN. In this paper, various S-box circuit architectures were evaluated firstly and the twisted BDD with m=4 was proved as the fastest one. A fast SMS4 cipher VLSI implementation was completed based on the twisted BDD S-box architecture, and achieved over 200 MHz and 100 MHz maximal frequency on SMIC 0.18 mum and...
Grid over OBS/GMPLS is successfully demonstrated and a self-organized resource discovery and management scheme is proposed for consumer Grid. High-speed TCPs for Grid are experimentally compared.
