36-to-9 Funneling Through FIFO #1

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 D0B – D35B, 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.
