subleaf

名词 n.

英文释义

名词 n.
  1. A smaller leaf making up part of a larger leaf. rare
    — The arrangement of the blades can be as simple as a single blade attached to the stem, or as complicated as subleaves occupying a single petiole, called a compound leaf. Even more complex are the double-compound leaves, with sub-subleaves making up subleaves that make up a larger leaf.
  2. A particular value of the ECX register when a program runs the CPUID instruction within a certain leaf (the value of EAX); each subleaf represents a specific category of information returned about the processor.
    — When CPUID executes with EAX set to 07H and the input value of ECX is invalid (see leaf 07H entry in Table 1-17), the processor returns 0 in EAX/EBX/ECX/EDX. In subleaf 0, EAX returns the maximum input value of the highest leaf 7 sub-leaf, and EBX, ECX & EDX contain information of extended feature flags.
