An event in which two or more processes belonging to some implicit or explicit group block until all members of the group have blocked. They may then all proceed. No member of the group may pass a barrier until all processes in the group have reached it. See also fuzzy barrier . A section of program that does not cross any conditional branches, loop boundaries or other transfers of control.
Most compiler optimization is done within basic blocks.
A collection of benchmark results for many computer systems is available on line from the National Software Exchange . A sufficient condition for the independence of two sections of a program as stated by Bernstein in 1966. Bi-polar CMOS . BiCMOS is a merger of ECL and CMOS wafer processes allowing both types of circuit to exist on the same chip. This gives the advantage of the small feature size and large scale integration of CMOS with ECL's high power, fast driver circuits.
