-- File: hibi_dct.vhd |
-- Creation date: 12.02.2013 |
-- Creation time: 10:33:28 |
-- Description: DCT to Hibi. Connects dctQidct block to HIBI Wrapper |
-- Creation date: 25.03.2013 |
-- Creation time: 13:53:33 |
-- Description: This block combines dct to hibi dctQidct block together |
-- |
-- 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. |
