The code is executed without blinking. How nice is it to increase by 15 times? Continue OptimizationMany 32-bit CPUs of embedded systems have at least two ALUs. Can we run both ALUs?

In the campus network market, the brocade company, whether it is a foreign Cisco, or the domestic Huawei, H3C, are not to be underestimated opponents. And the campus network is a new business growth point that brocade cannot abandon. How can we stand out from the market of strong competitors? "We have to do products that no one else has," said Yuzhanyun, a technology manager at Bo Ke's China area. Only by realizing the differentiation of product function, can we take a foothold in the network ma

: At the very beginning of the two conductors A0 and A1, the first one has electricity, the second is no power, you can know that this is an operation instruction (not a memory operation or a jump, etc.). Then the instruction will be fed into the logic unit (ALU) to calculate. It's actually very simple. As long as these two wires control the next part of the circuit switch. The next A2 and a3,01 represent addition, then go to the addition

Common MCUs are 8-bit, 16-bit, 32-bit, 64-bit, and 4-bit earlier (and, of course, now in use), as for 128-bit? Maybe it's PowerPC, but it doesn't seem to be part of the MCU's range.So how do we divide this "bit"?Depends on the width of the internal data bus of the internal data bus width.There are two types of architectures for MCUs today:1. von Neumann structure (Von-neumann Architecture) or (Princeton Architecture (Princetion Architecture))PM (program memory) and DM (Data memory) Two memory sh
