Thumb

(processor)
An extension to the Advanced RISC Machine architecture, announced on 06 March 1995 by Advanced RISC Machines Ltd. By identifying the critical subset of the ARM instruction set and encoding it into 16 bits, ARM has succeeded in reducing typical program size by 30-40% from ARM's already excellent code density. Since this Thumb instruction set uses less memory for program storage, cost is further reduced.

All Thumb-aware processor cores combine the capability to execute both the 32-bit ARM and the 16-bit Thumb instruction sets. Careful design of the Thumb instructions allow them to be decompressed into full ARM instructions transparently during normal instruction decoding without any performance penalty. This differs from other 32-bit processors, like the Intel 486SX, with a 16-bit data bus, which require two 16-bit memory accesses to execute every 32-bit instruction and so halve performance.

The patented Thumb decompressor has been carefully designed with only a small amount of circuitry additional to the existing instruction decoder, so chip size and thus cost do not significantly increase. Designers can easily interleave fast ARM instructions (for performance critical parts of a program) with compact Thumb code to save memory.

(jargon)
The slider or "bubble" on a window system scrollbar. So called because moving it allows you to browse through the contents of a text window in a way analogous to thumbing through a book.

(2) (Thumb) An extension to the architecture of an ARM chip that provides enhanced code density. It stores a subset of 32-bit instructions as compressed 16-bit instructions and decompresses them back to 32 bits upon execution. See ARM chips.

Cuticle thickness at the point of failure was measured by orienting the fracture surface of the broken pollex towards the viewer so that the line of sight was parallel to the occlusal surface of the pollex (line u, [ILLUSTRATION FOR FIGURE 1 OMITTED]).
c = distance from the neutral axis of the pollex to the upper surface (H/2, where H = height of the pollex parallel to the load vector immediately below the point of crack initiation, in mm: [ILLUSTRATION FOR FIGURE 1 OMITTED]).
Pollex short, stout, hooked at tip; a large ridge-like tooth occupying entire central portion; a deep notch at gape.
There were two thick nerve bundles in the intact propodus of the second cheliped [ILLUSTRATION FOR FIGURE 6A OMITTED]: one ran toward its dactyl along the boundary between the opener and closer muscles; the other ran to its pollex along the closer muscle.
In the propodus it was observed that one nerve trunk runs in the direction of the pollex and another to the dactyl.
To see whether the host site could regulate the morphology of the regenerated claw, different claw tissues (dactyl or pollex) or combinations of claw tissues (dactyl + pollex, ischium + merus/carpus joint, or dactyl + pollex + ischium) were contralaterally autotransplanted into eye sockets.
Thus, the coxa and ischium are proximal segments of the claw; the dactyl and pollex are the distal "digits" of a claw.
