<spirit:description>DCT to Hibi. Connects dctQidct block to HIBI Wrapper |
|
|
Input: |
1. Two address to send the results to (one for quant, one for idct) |
1. Address to send the results to quant |
2. Address to send the results to idct (set unused address if you don't use this) |
2. Control word for the current macroblock |
Control word structure: bit 6: chroma(1)/luma(0), 5: intra(1)/inter(0), |
4..0: quantizer parameter (QP) |
Control word structure: bit 6: chroma(1)/luma(0) (NOT USED), |
5: intra(1)/inter(0), |
4..0: quantizer parameter (QP) |
3. Then the DCT data ( 8x8x6 x 16-bit values = 384 x 16 bit ) |
|
Chroma/luma: 4 luma, 2 chroma |
Only 9b DCT data values are supported currently. |
Send two DCT-values packed to upper and lower 16bits in the sigle hibi transmission. |
|
<31------------------16--------------------0> BIT index |
DCT_DATA_1 DCT_DATA_0 DATA |
|
|
NOTE: If self release is used (use_self_rel_g=1) user gets the signal that dct_to_hibi is ready to receive data. |
By default self release is disabled and you user can send data to dct_to_hibi after quant results are received. |
|
|
Outputs: |
Outputs are 16-bit words which are packed up to hibi. If hibi width is |
32b, then 2 16-bit words are combined into one hibi word. |
