Abstract
VLIW processors are viewed as an attractive way of achieving instruction-level parallelism because of their ability to issue multiple operations per cycle with relatively simple control logic. They are also perceived as being of limited interest as products because of the problem of object code compatibility across processors having different hardware latencies and varying levels of parallelism. In this paper, we introduce the concept of delayed split-issue and the dynamic scheduling hardware which, together, solve the compatibility problem for VLIW processors and, in fact, make it possible for such processors to use all of the interlocking and scoreboarding techniques that are known for superscalar processors.
