How can I change the deflate core data bus width?

[jackylinpda]

In my current design, input data width is 256bit.
In deflate.v, the input i_data & output o_byte are 8bit.
How can I extend the data bus to 256bit?

you would have to write interface logic which converts from 1 256bit word to 8 8bit byte IO operations and uses an 8 byte buffer. The deflate algorithm is byte stream oriented by design.
