0740-7475/01/$10.00 © 2001 IEEE September–October 2001 THE DIGITAL SET-TOP BOX receiver is a key element in the worldwide deployment of digital television (DTV) and related interactive services. First-generation set-top boxes were quite simple with support only for channel-tuning and audiovideo data decoding. Increasingly, however, they are used as a(More)
Mobile satellite services are attracting renewed attention stemming from the FCC ancillary terrestrial component ruling that allows satellite spectrum to be used for integrated terrestrial services in the footprint of the satellite. This attention is focused on the development of dual-mode satellite-terrestrial devices to facilitate hybrid(More)
This paper introduces an automated transistor sizing tool (ASAP) that incorporates accurate gatelevel functio~nal models and can be used for delay, area, and power optimization of CMOS combinational logic circuits in a VLSI design environment. ASAP considers the performailce improvement of VLSI CMOS circuits by optimally sizing the transistors on the first(More)
Objective: The present study was intended to examine whether administration of aqueous extract of the Curry leaves (Murraya koenigii L.) do possess a protective effect against cadmium-induced oxidative stress in rat liver. Methods: Male albino rats used for present studies were divided in to four groups; control, cadmium treated, aqueous extract protected(More)
The ethanol extract of Cyperus rotundus (EECR) was tested for possible pharmacological effects on experimental animals. EECR significantly potentiated the sleeping time of mice induced by standard hypnotics, viz. pentobarbitone sodium, diazepam, and meprobamate in a dose dependent manner. EECR showed significant analgesic properties as evidenced by the(More)
Treatment of rats with a low dose of cadmium chloride caused a significant damage in the rat cardiac tissue indicated by the increase in the level of serum glutamate oxaloacetate transaminase and lactate dehydrogenase1 activities. Histological studies confirmed the damage due to cadmium. That cadmium-induced tissue damage was caused due to oxidative stress(More)
This paper represents a design study of the datapath for a very long instruction word (VLIW) video signal processor (VSP). VLIW architectures provide high parallelism and excellent high-level language programmability, but require careful attention to VLSI and compiler design. Flexible, highbandwidth interconnect, high-connectivity register files, and fast(More)
This paper presents a new simple but accurate delay model for both simple and complex static logic gates. Uiilike the previous delay modles which assume the worst case scenario, our delay model has the capability to handle the different input switching conditions. In the delay analysis of a circuit, failing to take into account the position of the(More)
