Peter Robinson and David Hyland-Wood described how Solidity code is compiled, deployed, and executes in the Ethereum Virtual Machine. The talk covers EVM opcodes and how code in the EVM uses the various data locations:
Stack: EVM Opcodes pop information from and push data onto the stack.
CallData: Transaction parameters.
Memory: Temporary data store within a transaction.
Storage: Persistent storage that is part of world state.
Code: Stores code and static data such as strings.
Logs: Write-only event log output.
