an example of the most complex interface possible, Figure 8.5 assumes
that each byte-wide SRAM needs to be split into four blocks (see
word-wide SRAM in Section 8.5.2, “FOURSEGX32,”).
In Section 8.5.2, “FOURSEGX32,” the SRAM Address is 11 bits. Bits
[12:11] of the address are used to decode which of the four word-wide
RAMs is selected.
In Figure 8.5, ByteWrite[3:0] is used (inside
IRamIF.v
) to decode each
word-wide chip select into four separate chip select signals, one for each
byte of the word.
