TAILIEUCHUNG - Lecture Computer organization and assembly language - Lecture 05: Memory Access

This chapter presents the following content: Assembly language programming - Moving up a level, an assembly language program, the assembly process, beyond the assembly of a single assembly language program. | CSC 221 Computer Organization and Assembly Language Lecture 05: Memory Access Lecture 4: Review The programming model of the 8086 through 80286 contain 8- and 16-bit registers. The programming model of the 80386 and above contains 8-, 16-, and 32-bit extended registers as well as two additional 16-bit segment registers: FS and GS. Lecture 4: Review The 64-bit registers in a Pentium 4 with 64-bit extensions are RAX, RBX, RCX, RDX, RSP, RBP, RDI, RSI, and R8 through R15. In addition, the microprocessor contains an instruction pointer (IP/EIP/RIP) and flag register (FLAGS, EFLAGS, or RFLAGS). (cont.)
