13.1.1. NEON media coprocessor

The NEON coprocessor is the ARM Single Instruction Multiple Data (SIMD) media processing architecture. It is part of ARMv7-A. The components of the NEON coprocessor are:

The NEON coprocessor can receive up to two valid NEON instructions per cycle from the ARM integer instruction execute unit. NEON load data can be retrieved from either the L1 data cache or the L2 memory system. In addition, it can receive 32-bit MCR data from or send 32-bit MRC data to the ARM integer instruction execute unit.
