Nettet24. feb. 2024 · The sizes of these two objects are different - 24 bytes and 16 bytes. This has to do with the ordering of the data members. In the foo1 structure, p needs to be aligned at the address that is divisible by 8, so the int and short before it will occupy 8 bytes in total and two chars after it will occupy the 8 bytes as well. Nettet25. mar. 2024 · The instruction stream is represented as series of bytes known as opcode. Modern CPUs fetch the opcodes of instructions in chunks of 16-bytes (16B), 32-bytes (32B) or 64-bytes (64B). The CISC architecture has variable length encoding, meaning the opcode representing each instruction in the instruction stream is of …
