Abstract
In an embodiment, a scheduler implements a first dependency array that tracks dependencies on instruction operations (ops) within a distance N of a given op and which are short execution latency ops. Other dependencies are tracked in a second dependency array. The first dependency array may evaluate quickly, to support back-to-back issuance of short execution latency ops and their dependent ops. The second array may evaluate more slowly than the first dependency array.
