24 Sep 2003 The Thumb instruction set consists of 16-bit instructions that act as a compact shorthand for a subset But the narrower 16-bit instructions do offer memory advantages. In the ARM state, 17 registers are visible in user mode.
ARM® and Thumb®-2 Instruction Set B meaning half-register [15:0], or T meaning [31:16].

"The Thumb instruction set is a subset of the most commonly used 32-bit ARM instructions.Thumb instructions are 16 bits long,and have a corresponding 32-bit ARM instruction that has the same effect on processor model."
