SP (FP) [MFLOP/s] = 1E-06*FP_SP_FIXED_OPS_SPEC/time
SP (FP+SVE128) [MFLOP/s] = 1.0E-06*(FP_SP_FIXED_OPS_SPEC+((FP_SP_SCALE_OPS_SPEC*128)/128))/time
SP (FP+SVE256) [MFLOP/s] = 1.0E-06*(FP_SP_FIXED_OPS_SPEC+((FP_SP_SCALE_OPS_SPEC*256)/128))/time
SP (FP+SVE512) [MFLOP/s] = 1.0E-06*(FP_SP_FIXED_OPS_SPEC+((FP_SP_SCALE_OPS_SPEC*512)/128))/time

Single-precision FP rate for scalar and SVE vector operations with different widths. The events for
the SVE metrics assumes that all vector elements are active.
