usage bit

You may surf the Web a bit too long at times, but you have control over your usage.

你在网上冲浪的时间偶尔会稍微多一些，但你对上网还是有自控能力的。

In this dissertation, some approaches are given to optimize the memory usage of SOC. Since the MPEG-2 decoding chip is a SOC, 32-bits embedded RISC CPU core is used to decode the AC3 and TS bit stream.

论文设计的MPEG-2系统集成解码芯片是一个SoC，该SoC采用32位嵌入式RISC CPU核Virgo进行音频AC3和TS流解码的计算任务，并承担SoC的管理；

The usage of error correcting codes can lower the bit-error rate ( BER) in digital communication systems and data storage systems, and hence improves the communication quality.

利用纠错码可以降低数字通信系统以及数据存储系统的误码率，改善通信质量。
