Thus far, we have gained some acquaintance with certain basic aspects of Assembly programming. We have covered the Intel Architecture basics, setting up the development environment of your choice, and the instruction set architecture (ISA).
We know what operations we are able to perform over different types of data, but all this is of very little value as long as we don't know how to retrieve and store data. Of course, we are familiar with the mov instruction, but without knowing how to address the data in memory, this instruction is quite useless.
Fortunately for us, Intel provides a very flexible mechanism for addressing data or code in memory. In this chapter, we will cover the following modes of memory addressing:
- Sequential addressing
- Direct addressing
- Via an immediate address
- Via an address stored in a register
- Indirect addressing
- Via an...
