A peripheral system, such as a tape data storage system, disk data storage system, printing system, or communication system, may attach to a diversity of host processors having diverse operating characteristics. A first type A may operate in a tightly knit fashion such that timing of data transfers is highly predictable, enabling the peripheral system to operate in a relatively fixed manner. Other host processors, which may include loosely-coupled multiprocessing systems, may operate in a variable timing mode such that the predictability of data transfers with respect to a given peripheral system may be low. This is termed as variable-timing host processing.
