On-Chip Communication Architectures

313

An interesting discussion on CDMA and other advanced interconnects, such as

frequency division multiple access (FDMA), was presented by Chang [31]. FDMA

interconnects allow sharing of bus lines by assigning different data fl ows to differ-

ent frequency channels. Data fl ows assigned to different frequency channels can

communicate concurrently with virtually no interference, provided that undesired

frequency channels are fi ltered out at the destination. The FDMA and CDMA can

also be combined into a hybrid multi-carrier CDMA scheme, where concurrent

data fl ows are possible by assigning appropriate codes and frequencies to each

data fl ow pair ...
