Table 8-22. Cpuid Instruction With Eax = 80000002H, 80000003H, Or 80000004H - AMD Geode LX 600@0.7W Data Book

Instruction Set
8.2.2.3 CPUID Instruction with EAX = 80000002h, 80000003h, or 80000004h
Extended functions 80000002h through 80000004h (EAX = 80000002h, EAX = 80000003h, and EAX = 80000004h) of the
CPUID instruction returns an ASCII string containing the CPU marketing name, as shown in Table 8-22. These functions
eliminate the need to look up the processor name in a lookup table. Software can simply call these functions to obtain the
name of the processor. The string may be 48 ASCII characters long, and is returned in little endian format. If the name is
shorter than 48 characters long, the remaining bytes are filled with ASCII NUL characters (00h).
