摘要： A method for recording a complete stream of live data packets from a server in a media cache with reduced server-cache bandwidth includes utilizing a first amount of server-cache bandwidth to receive only a portion of the complete stream of live data packets from the server, determining when the stream of live data packets from the server finishes, thereafter utilizing a second amount of server-cache bandwidth to receive missing portions of the complete stream of live data packets, and combining the portion of the complete stream of live data packets and the missing portions of the complete stream of live data packets to form the complete stream of live data packets in the memory.

摘要： A shorted resistive block formed in line with at least one trace of a plurality of a top metal layer includes a plurality of resistors with a removable shorting link coupled across the resistive block. The resistive block comprises one of a plurality of series coupled shorted resistors and a shorted plurality of parallel coupled resistors. If harmonic interference needs to be reduced, a short is removed and the resistive block is operably coupled to parasitic capacitance thereby creating an R-C filter. The real performance is re-evaluated after removing the short. If the re-evaluation determines a desired R-C filter value should be increased, the resistance of the resistive block is increased by opening a shorting link. In the series configured resistive block, resistance is increased by removing a short across a resistor. In the parallel configuration, the resistance is increased by cutting a removable link coupled in series with each resistor.
摘要翻译：形成为与多个顶部金属层的至少一个迹线对齐的短路电阻块包括多个电阻器，其具有耦合在电阻块上的可移除的短路链路。电阻块包括多个串联耦合的短路电阻器中的一个和短路的多个并联的电阻器。如果需要降低谐波干扰，则消除短路，并将电阻块可操作地耦合到寄生电容，从而产生R-C滤波器。删除短片后，真正的表现被重新评估。如果重新评估确定需要增加所需的R-C滤波器值，则通过打开短路链路来增加电阻块的电阻。在串联配置的电阻块中，通过去除电阻之间的短路来增加电阻。在并联配置中，通过切割与每个电阻串联耦合的可拆卸连接来增加电阻。

摘要： The present invention adds a plurality of substrate barriers for reducing substrate noise. The barriers, consisting of a plurality of equally sized n-well regions formed within the p-substrate, are formed between the analog and digital portions and on at least one side of sensitive analog circuits. A MOSFET transistor configured as a capacitor is formed within each of the n-well regions and is coupled between supply and circuit common to filter supply noise. A metal layer capacitor is formed above each MOSFET capacitor and is coupled between supply and circuit common. The present inventive circuit adds metallization to satisfy metal percentage requirements and to improve noise filtering. Each barrier region includes a plurality of coupled (shorted) n-wells with MOSFET transistors configured as capacitors. Additionally, in the described embodiment, the metallization layer is formed to create metal capacitors on top layers of the n-well regions to create additional noise filtering between supply and ground.
