PORT B WORD-WIDTH SELECTION
NOTES:
1.
The heavy black borders on register segments indicate the main
data path, suitable for most applications. Alternate paths feature
a different ordering of bytes within a word, at Port B.
2.
The funneling process does not change the ordering of bits within
a byte. Halfwords (Figure 6a) or bytes (Figure 6b) are trans-
ferred in parallel form from Port A to Port B.
3.
The word-width setting may be changed during system operation;
however, two clock intervals should be allowed for these signals
to settle, before again attempting to read D
– D
, and three
dummy words should be passed through initially. Also, incom-
plete data words may occur, when the word width is changed
from shorter to longer at an inappropriate point in the data block
passing through the FIFO.
