Offset in memory management

Webb11 jan. 2024 · The indexes of a linear memory array can be considered memory addresses, and instructions that need to access a memory location are given an offset relative to the start of the memory. This ensures a few important things related to memory safety in WebAssembly (assuming the runtime implementation is bug-free): WebbIn some embodiments, an apparatus includes a memory and a processor. The processor is configured to receive an intent command from a control device. The processor is configured to identify, based on the intent command, a first portion of an image captured by a first image capture device and to identify, using video analytics, a second portion of …
