Reduced instruction set computer RISC architectures. In practice, since the specific implementation details of proprietary TrustZone implementations have not been publicly disclosed for review, it is unclear what level of assurance is provided for a given threat modelbut they are not immune from attack.

Single-board microcontroller Special function register. They seem to give the closest answer to what you are looking for. Retrieved 6 February The VFP architecture was intended to support execution of short “vector mode” instructions but these operated on each vector element sequentially and thus did not offer the performance of true single instruction, multiple data SIMD vector parallelism. In Thumb, the bit opcodes have less functionality. referencw
