11 
        DCT to Hibi. Connects dctQidct block to HIBI Wrapper
12 
 
13 
 
14 
Input:
15 
1. Two address to send the results to (one for quant, one for idct)
16 
2. Control word for the current macroblock
17 
    Control word structure: bit 6: chroma(1)/luma(0), 5: intra(1)/inter(0),
18 
                             4..0: quantizer parameter (QP)
19 
3. Then the DCT data ( 8x8x6 x 16-bit values = 384 x 16 bit )
20 
 
21 
Chroma/luma: 4 luma, 2 chroma
22 
 
23 
Outputs:
24 
 Outputs are 16-bit words which are packed up to hibi. If hibi width is
25 
 32b, then 2 16-bit words are combined into one hibi word.
26 
 01. quant results: 1. 8*8 x 16bit values to quant result address
27 
 02. idct  results: 1. 8*8 x 16bit values to idct  result address
28 
 03. quant results: 2. 8*8 x 16bit values to quant result address
29 
 04. idct  results: 2. 8*8 x 16bit values to idct  result address
30 
 05. quant results: 3. 8*8 x 16bit values to quant result address
31 
 06. idct  results: 3. 8*8 x 16bit values to idct  result address
32 
 07. quant results: 4. 8*8 x 16bit values to quant result address
33 
 08. idct  results: 4. 8*8 x 16bit values to idct  result address
34 
 09. quant results: 5. 8*8 x 16bit values to quant result address
35 
 10. idct  results: 5. 8*8 x 16bit values to idct  result address
36 
 11. quant results: 6. 8*8 x 16bit values to quant result address
37 
 12. quant results: 1 word with bits 5..0 determing if 8x8 quant blocks(1-6)
38 
                    has all values zeros (except dc-component in intra)
39 
 13. idct  results: 6. 8*8 x 16bit values to idct  result address
40 
-
41 
 Total amount of 16-bit values is: 384 per result address + 1 hibi word to
42 
 quantization result address.
43 
 
44 
 With default parameter:
45 
 Total of 193 words of data to quant address (if data_width_g = 32)
46 
 Total of 192 words of data to idct address (if data_width_g = 32)
