        This block combines dct to hibi dctQidct block together

DCT_TO_HIBI Connects dctQidct block to HIBI Wrapper
14 152 lanttu 
 
15 
Input:
16 169 lanttu 
1.  Address to send the results to quant
17 
2.  Address to send the results to idct (set unused address if you don't use this)
18 152 lanttu 
2. Control word for the current macroblock
19 169 lanttu 
    Control word structure: bit    6: chroma(1)/luma(0) NOT USED,
20 
                                5: intra(1)/inter(0),
21 
                                                   4..0: quantizer parameter (QP)
22 152 lanttu 
3. Then the DCT data ( 8x8x6 x 16-bit values = 384 x 16 bit )
23 
 
24 169 lanttu 
Only 9b DCT data values are supported currently.
25 
Send two DCT-values packed to upper and lower 16bits in the sigle hibi transmission.

            DCT_DATA_1         DCT_DATA_0     DATA
29 
 
30 
 
31 
NOTE: If self release is used (use_self_rel_g=1) user gets the signal that dct_to_hibi is ready to receive data.
32 
            By default self release is disabled and you user can send data to dct_to_hibi after quant results are received.

Outputs:
36 
 Outputs are 16-bit words which are packed up to hibi. If hibi width is
37 
 32b, then 2 16-bit words are combined into one hibi word.
38 
 01. quant results: 1. 8*8 x 16bit values to quant result address
39 
 02. idct  results: 1. 8*8 x 16bit values to idct  result address
40 
 03. quant results: 2. 8*8 x 16bit values to quant result address
41 
 04. idct  results: 2. 8*8 x 16bit values to idct  result address
42 
 05. quant results: 3. 8*8 x 16bit values to quant result address
43 
 06. idct  results: 3. 8*8 x 16bit values to idct  result address
44 
 07. quant results: 4. 8*8 x 16bit values to quant result address
45 
 08. idct  results: 4. 8*8 x 16bit values to idct  result address
46 
 09. quant results: 5. 8*8 x 16bit values to quant result address
47 
 10. idct  results: 5. 8*8 x 16bit values to idct  result address
48 
 11. quant results: 6. 8*8 x 16bit values to quant result address
49 
 12. quant results: 1 word with bits 5..0 determing if 8x8 quant blocks(1-6)
50 
                    has all values zeros (except dc-component in intra)
51 
 13. idct  results: 6. 8*8 x 16bit values to idct  result address
52 
-
53 
 Total amount of 16-bit values is: 384 per result address + 1 hibi word to
54 
 quantization result address.
55 
 
56 
 With default parameter:
57 
 Total of 193 words of data to quant address (if data_width_g = 32)
58 
 Total of 192 words of data to idct address (if data_width_g = 32)
