The challenge is being able to identify a reliable, low-risk, level of con dence method of determining values for statistically variant parameters. This chapter describes how we allocate System Performance Speci cation (SPS) requirements to lower levels. We explore how functional and nonfunctional performance are analyzed and allocated. This requires building on previous practices such as statistical in uences on system design discussed in the preceding chapter. We introduce the concepts of decomposing cycle time based performances into queue, process, and transport times. Finally, we conclude by illustrating how performance budgets and safety margins enable us to achieve SPS performance requirements.

is generated from k message bits with a rst bipartite graph, as explained above. Then, a second graph is added starting from the check bits of the previous graph. Thus the new graph has k left bits and 2 k right bits. Then, a further graph can be added with 2 k left bits and 3 k right bits, and so on. More formally, it should be said that a set of codes C(B0 ), C(B1 ), ..., C(Bm ) is constructed by means of a set of bipartite graphs B0 , B1 , . . . , Bm , where a generic graph Bi has i k left nodes and i+1 k right nodes. The value m is chosen such that m+1 k is roughly k. The check bits of the last graph are nally encoded via another erasure code, say C, which can be, for example, a Reed Solomon code as proposed in reference 27. In Figure 4.7 the last level erasure code is a systematic code with left nodes as original data and right nodes as redundant data. The nal code includes the original k message bits, the check bits produced by the bipartite graphs at the m different levels, and the last-level RS code. The entire code can be referred to as C (B0 ,B1 ,B2 , . . . , Bm ,C). Given k the number of original message bits, the total number of check bits is as follows.

Design-to MOP A targeted mean value bounded by minimum and/or maximum threshold values levied on a system capability performance parameter to constrain decision making. Performance Budget Allocation A minimum, maximum, or min-max constraint that represents the absolute thresholds that bound a capability or performance characteristic. Processing Time The statistical mean time and tolerance that statistically characterizes the time interval between an input stimulus or cue event and the completion of processing of the input(s). Queue Time The statistical mean time and tolerance that characterizes the time interval between the arrival of an input for processing and the point where processing begins. Safety Margin A portion of an assigned capability or physical characteristic measure of performance (MOP) that is restricted from casual usage to cover instances in which the budgeted performance exceeds its allocated MOP. System Latency The time differential between a stimulus or cue events and a system response event. Some people refer to this as the responsivity of the system for a speci c parameter. Transport Time The statistical mean time and tolerance that characterizes the time interval between transmission of an output and its receipt at the next processing task.

Every functional capability or physical characteristic of a system or item must be bounded by performance constraints. This is very important in top-down/bottom-up/horizontal design whereby system functional capabilities are decomposed, allocated, and owed down into multiple levels of design detail.

Achieving Measures of Performance (MOPs)

i k + m+2 k/(1 ) = k (1 ).

The mechanism for decomposing system performance into subsequent levels of detail is referred to as performance budgets and margins. In general, performance budgets and margins allow SEs to impose performance constraints on functional capabilities that include a margin of safety. Philosophically, if overall system performance must be controlled, so should the contributing entities at multiple levels of abstraction. Performance constraints are further partitioned into: 1) design-to measures of performance (MOPs) and 2) performance safety margins.
