In the chart above, it can be seen that when using hardware acceleration (NEON&VFPv4 extension), no reduction is achieved in the CPU workload. The average difference between CPU_0_accel and CPU_1_unaccel is 0.5 % more load for CPU_0_accel. The average difference between CPU_1_accel and CPU_0_unaccel is 0.125 % more load for CPU_1_accel. | In the chart above, it can be seen that when using hardware acceleration (NEON&VFPv4 extension), no reduction is achieved in the CPU workload.

In the chart above, it can be seen in a general way that when using hardware acceleration (NEON&VFPv4 extension), a lees buffer processing time is achieved. The average difference per buffer is 17.47 us when hardware acceleration (NEON&VFPv4 extension) is used. | |||
