Connects dctQidct block to HIBI WrapperInput:1. Address to send the results to quant2. Address to send the results to idct (set unused address if you don't use this)2. Control word for the current macroblockControl 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 )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 indexDCT_DATA_1 DCT_DATA_0 DATANOTE: 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 is32b, then 2 16-bit words are combined into one hibi word.01. quant results: 1. 8*8 x 16bit values to quant result address02. idct results: 1. 8*8 x 16bit values to idct result
