DS1307 RTC 使用 8051 通过 I2C 协议

经过定点优化的G723、G729的codec In case you do not want to install IPP, then you"ll get twice better performance out of ITU-T code if you build it with GCC 4.5 or Intel CC with LTO/IPO enabled. Still, even with ICC, it is 10x slower than IPP - 30ms vs 3ms of processor time to encode one second of G.729 audio on modern hardware. G.723 is around 100ms. GCC with LTO is 2x slower than ICC. For ITU-T code, a Core2 class processor is recommended.
