当你作为 Solidity 开发者开始写 Ethereum 智能合约的时候，你会很快接触到一些概念像是EVM（Ethereum Virtual Machine），bytecode 和 ABI（application binary interface），如果你是一个 Javascript 开发者（就像我第一次学习代码的时候一样），这些专有名字可能对你来说并不陌生 ...

零中频接收机下变频到基带的两路IQ信号是用来表示调制信号的幅度和相位的。为了测试这两路信号的质量，我们可以使用误差矢量‍幅度(EVM)这个指标。EVM反映了信号在传输过程中受到的噪声、失真和干扰的影响。 EVM值越小，说明接收信号与理想信号之间的 ...

Ethereum co-founder Vitalik Buterin has proposed a major change to the network’s execution layer: replacing the Ethereum Virtual Machine (EVM) bytecode with the RISC-V instruction set. This shift ...

大多数射频工程师都会接受有关大量射频性能参数的培训，例如噪声系数、三阶截取点和信噪比。了解这些性能参数对整体系统级性能的综合影响可能极具挑战性。EVM不评估多个单独的性能指标，而是反映整个系统的概况。在本文中，ADI将分析较低水平的性能 ...

At the heart of ethereum lies a virtual computer. Stored across tens of thousands of nodes that make up the platform, the ethereum virtual machine, or EVM, is responsible for executing the countless ...

The new decompiler lets the developers revert difficult to understand EVM bytecode back to its original state and can be scanned to check for susceptibility to new attacks or to ensure adherence to ...
