SDECFG_ARM_THUMB
|
|
Controls whether to utilize the ARM Thumb instruction set or not.
|
|
Thumb is an extension to the 32-bit ARM architecture. It features
|
|
a subset of the most commonly used 32-bit ARM instructions which
|
|
have been compressed into 16-bit wide opcodes. On execution, these
|
|
16-bit instructions are decompressed transparently to full 32-bit
|
|
ARM instructions in real time without performance loss.
|
|
The use of the Thumb extension usually increases code density,
