++ * VFP is a floating point coprocessor used in some ARM cores. VFP11 has 1 cycle
++ * throughput for almost all the instructions (except for double precision
++ * arithmetics), but rather high latency. Latency is 4 cycles for loads and 8 cycles
++ * for arithmetic operations. Scheduling code to avoid pipeline stalls is very
++ * important for performance. One more interesting feature is that VFP has
++ * independent load/store and arithmetics pipelines, so it is possible to make
++ * them work simultaneously and get more than 1 operation per cycle. Load/store
++ * pipeline can process 2 single precision floating point values per cycle and
++ * supports bulk loads and stores for large sets of registers. Arithmetic operations
++ * can be done on vectors, which allows to keep the arithmetics pipeline busy,
++ * while the processor may issue and execute other instructions. Detailed
++ * optimization manuals can be found at http://www.arm.com
