Address computation in TComPicYUV and TComDataCU relies on use of division and modulo operations. In many cases the denominator is a power of 2 but there is no way for a compiler to figure it out. It would be desirable to make use of bit shift and and operations to lessen the burden of address computation. In some cases use of pre-computed look-up tables would also be beneficial (e.g., when deriving an address within a picture based on a linear CU address).
