First of all, let us try to build a "half adder", one that takes in two bits and adds them to output two bits.Let us think one bit at a time and take the first bit at first.However, in practice there are two kinds of memory structures: static RAM (or SRAM in short), which uses 6 transistors per bit, and dyna... 阅239 转5 评0 公众公开 14-10-06 17:25 |

Athlon 64 X2:真假双核的口水战]2005年Intel率先发布了双核处理器——Pentium D系列,此时AMD的双核处理器未上市,但是真刀真枪还未登场,口水仗先打起来了,AMD指责Intel的双核处理器并非真双核,充其量只是双芯,是在欺骗消费者。X2的发布代表着AMD双核时代的到来源自K8的优良架构使得AMD的双核处理器性能非常强劲,可以轻易地在测试和游戏... 阅435 转11 评0 公众公开 11-02-18 14:25 |
随着电子设备越来越复杂,需要的元器件越来越多,PCB上头的线路与元器件也越来越密集了。另一方面,SMT也比THT的元器件要小,和使用THT元器件的PCB比起来,使用SMT技术的PCB板上元器件要密集很多。因为目前PCB的生产过程中均采用全自动技术,尽管SMT元器件的安装焊点和元器件的接脚非常小,倒不会增加生产中的难度,不过,当出现故障维修时如果... 阅8530 转254 评1 公众公开 09-12-23 17:54 |
