A processor with a 32-bit memory address register can directly access up to how much physical RAM address space?
When an x86 processor operates in protected mode, the 16-bit value loaded into a segment register is called a __________.
In x86 protected mode, what does the acronym IDT stand for?
The Motorola 68000 (68K) processor architecture features how many 32-bit general-purpose registers in total (comprising 8 data registers D0–D7 and 8 address registers A0–A7)?
In Motorola 68K processors, the Program Counter (PC) register that holds the address of the currently executing/next instruction has a width of __________.
Motorola 68K processors feature how many total 32-bit general-purpose registers (combining 8 data registers D0-D7 and 8 address registers A0-A7)?
In Motorola 68K processors, there is a 32-bit __________ register that holds the physical memory address of the currently executing instruction.
How many standard function calling conventions are commonly used in high-level programming languages? State their names.
Translate the following 32-bit x86 assembly routine into an equivalent C language function:
```assembly
global swap
swap:
mov ecx, [esp+4] ; copy parameter p1 to ecx
mov edx, [esp+8] ; copy parameter p2 to edx
mov eax, [ecx] ; copy *p1 to eax
xchg eax, [edx] ; exchange eax with *p2
mov [ecx], eax ; copy eax to *p1
ret ; return
```
