| CABAC throughput (Test 6)
More efficient coding of the syntax elements in Intra String Copy.
Input documents: JCTVC-S0165.
Constraints for run length and number of runs (Test 7)
It is required that for each proposal, the worst case memory bandwidth analysis shall be provided. In addition, it is suggested to provide statistics for the average memory bandwidth.
Input documents: JCTVC-S0174 and JCTVC-S0192.
A common CE10 software was used that supports 2D matching for Intra String Copy with horizontal scanning order within a CU.
The memory bandwidth analysis methodology for the horizontal scan order in 2D matching mode hasn’t been well established, as concluded in the previous meeting.
Some of the new tests, including e.g., Test 1 (vertical scan), Test 2 (1D matching) may have implications for different patterns of memory bandwidth access, while how to evaluate the complexity (including memory access) for those methods needs to be discussed.
In the following tables, 4-CTU restricts both IBC and string copy to the same search range.
