To improve performance, we break down the 16x4 matrix into 4 rows, rather than 4 squares. Thus strided loads and stores are avoided, and the 4 DC calculations are vectored.

It ends up slower overall, especially for VP7, as we then have to compute 16 DC's instead of just 4.

lavc/vp8dsp: rework R-V V idct_dc_add4y DCT-related FFmpeg functions often add an unsigned 8-bit sample to a signed 16-bit coefficient, then clip the result back to an unsigned 8-bit value. RISC-V has no signed 16-bit to unsigned 8-bit clip, so instead our most common sequence is: VWADDU.WV set SEW to 16 bits VMAX.VV zero # clip negative values to 0 set SEW to 8 bits VNCLIPU.WI # clip values over 255 to 255 and narrow Here we use a different sequence which does not require toggling the vector type. This assumes that the wide addend vector is biased by -128: VWADDU.WV VNCLIP.WI # clip values to signed 8-bit and narrow VXOR.VX 0x80 # flip sign bit (convert signed to unsigned) Also the VMAX is effectively replaced by a VXOR of half-width. In this function, this comes for free as we anyway add a constant to the wide vector in the prologue. On C908, this has no observable effects. On X60, this improves microbenchmarks by about 20%.

lavc/vp8dsp: add R-V V vp7_idct_dc_add4y As with idct_dc_add, most of the code is shared with, and replaces, the previous VP8 function. To improve performance, we break down the 16x4 matrix into 4 rows, rather than 4 squares. Thus strided loads and stores are avoided, and the 4 DC calculations are vectored. Unfortunately this requires a vector gather to splat the DC values, but overall this is still a win for performance: T-Head C908: vp7_idct_dc_add4y_c: 7.2 vp7_idct_dc_add4y_rvv_i32: 2.2 vp8_idct_dc_add4y_c: 6.2 vp8_idct_dc_add4y_rvv_i32: 2.2 (before) vp8_idct_dc_add4y_rvv_i32: 1.7 SpacemiT X60: vp7_idct_dc_add4y_c: 6.2 vp7_idct_dc_add4y_rvv_i32: 2.0 vp8_idct_dc_add4y_c: 5.5 vp8_idct_dc_add4y_rvv_i32: 2.5 (before) vp8_idct_dc_add4y_rvv_i32: 1.7 I also tried to provision the DC values using indexed loads. It ends up slower overall, especially for VP7, as we then have to compute 16 DC's instead of just 4.

lavc/vp8dsp: rework R-V V idct_dc_add4y DCT-related FFmpeg functions often add an unsigned 8-bit sample to a signed 16-bit coefficient, then clip the result back to an unsigned 8-bit value. RISC-V has no signed 16-bit to unsigned 8-bit clip, so instead our most common sequence is: VWADDU.WV set SEW to 16 bits VMAX.VV zero # clip negative values to 0 set SEW to 8 bits VNCLIPU.WI # clip values over 255 to 255 and narrow Here we use a different sequence which does not require toggling the vector type. This assumes that the wide addend vector is biased by -128: VWADDU.WV VNCLIP.WI # clip values to signed 8-bit and narrow VXOR.VX 0x80 # flip sign bit (convert signed to unsigned) Also the VMAX is effectively replaced by a VXOR of half-width. In this function, this comes for free as we anyway add a constant to the wide vector in the prologue. On C908, this has no observable effects. On X60, this improves microbenchmarks by about 20%.
