- * 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
