ther architecture alternatives, like wide superscalarand VLIW (very long instruction word), suffer fromdrawbacks---implementation complexity, low utilizationof resources, and immature compiler technology---or deliver only modest performance improve--ments. Moreover, they usually exacerbate the mainmemory bandwidth bottleneck.3Beyond the uniprocessor, the possibility exists forthe integration of multiple processors on a single die,but this integration would place even greater...
