6. 828 Lecture Notes: x86 and PC architecture Outline • PC architecture • x86 instruction set • gcc calling conventions • PC emulation PC architecture • A full PC has: o an x86 CPU with registers, execution unit, and memory management o CPU chip pins include address and data signals o memory o disk o keyboard o display o other resources: BIOS ROM, clock, . . . • We will start with the original 16-bit 8086 CPU (1978) • CPU runs instructions: • for(;;){ • run next instruction • } • Needs work space: registers o four 16-bit data registers: AX, CX, DX, BX o each in two 8-bit halves, e. g. AH and AL o very fast, very few • More work space: memory o CPU sends out address on address lines (wires, one bit per wire) o Data comes back on data lines o or data is written to data lines • Add address registers: pointers into memory o SP - stack pointer o BP - frame base pointer o SI - source index o DI - destination index • Instructions are in memory too! o IP - instruction pointer (PC on PDP-11, Menos
