The TI ASC (Advanced Scientific Computer) had one to four pipelines, but no scalar unit, which hurt performance badly. The designers underestimated the amount of scalar code in their target programs. Still, they sold more ASCs than CDC sold Star-100s. (Four, I believe.) -- Paul Suhler suhler@im4u.UTEXAS.EDU 512-474-9517/471-3903
