Abstract

While cycle stealing among n referencing registers on a priority interrupt basis from a common memory is broadly old, it is desirable to avoid lockout of some of the referencing registers. This can be resolved in part by limiting the number of cycles that can be "stolen" at any one time by a referencing register to no more than m out of n cycles, where m is less than n.
