SpacemiT X60: dct_unquantize_h263_inter_c: 417.8 ( 1.00x) dct_unquantize_h263_inter_rvv_i32: 66.0 ( 6.33x) dct_unquantize_h263_intra_c: 140.2 ( 1.00x) dct_unquantize_h263_intra_rvv_i32: 67.7 ( 2.07x) Note that the C benchmarks are not stable, depending heavily on the number of coefficients picked by the RNG. The R-V V benchmarks are however very stable and generally better than C's.
