Architecture exploration

Architectural exploration and behavioral partitioning. Micro-architecture generation. 

Once the behavioral description and the FU library are ready, Amical can be used for architectural exploration and synthesis. This step includes scheduling and allocation. The behavioral description is partitioned into a data-path and a controller. The synthesis can be carried out automatically, manually, or by a combination of both approaches. The automatic synthesis produces the fastest architecture according to the input description. This architecture may be manually modified in order to reduce the number of allocated FUs and busses (see section 4). 

Chain models capture the basic elements of the amphiphilic behaviour by retaining details of the molecular architecture. Ben-Shaul et aJ [ ] and others [ ] explored the organization of tlie hydrophobic portion in lipid micelles and bilayers by retaining the confonuational statistics of the hydrocarbon tail withm the RIS (rotational isomeric state) model [4, 5] while representing the hydrophilic/liydrophobic mterface merely by an... 

These chain models are well suited to investigate the dependence of tire phase behaviour on the molecular architecture and to explore the local properties (e.g., enriclnnent of amphiphiles at interfaces, molecular confonnations at interfaces). In order to investigate the effect of fluctuations on large length scales or the shapes of vesicles, more coarse-grained descriptions have to be explored. 

Given tire general description of tire electromagnetic field, let us explore the sources available for optoelectronics. The one primary light source for optoelectronic device and system architectures is tire laser. The laser [10] is tire source of choice simply because if we want to control light fields tliey need to be well defined at tire start and tire laser is tire most... 

Block copolymers can contain crystalline or amorphous hard blocks. Examples of crystalline block copolymers are polyurethanes (e.g. B.F. Goodrich s Estane line), polyether esters (e.g. Dupont s Hytrel polymers), polyether amides (e.g. Atofina s Pebax grades). Polyurethanes have enjoyed limited utility due to their relatively low thermal stability use temperatures must be kept below 275°F, due to the reversibility of the urethane linkage. Recently, polyurethanes with stability at 350°F for nearly 100 h have been claimed [2]. Polyether esters and polyether amides have been explored for PSA applications where their heat and plasticizer resistance is a benefit [3]. However, the high price of these materials and their multiblock architecture have limited their use. All of these crystalline block copolymers consist of multiblocks with relatively short, amorphous, polyether or polyester mid-blocks. Consequently they can not be diluted as extensively with tackifiers and diluents as styrenic triblock copolymers. Thereby it is more difficult to obtain strong, yet soft adhesives — the primary goals of adding rubber to hot melts. 

Since the chemical composition of a polymer defines its flow behavior, we will now explore the effects of molecular architecture, such as chain length, the presence of branching, and polarity on these properties. 

Because each quality attribute corresponds to a stakeholder performing an action on the system either at design time or at runtime, we can use scenarios of such interactions to explore and evaluate an architecture. The main difference here from our original use of the word scenario (see Section 4.7.4, Scenarios) is that now we are not restricted to only runtime behaviors but include scenarios of system modifications, reuse, and so on. 

In order to explore the properties that may be obtained by hybridizing the linear and dendritic architectural states, both diblock and triblock copolymer... 

Since that time, synthetic chemists have explored numerous routes to these statistically hyperbranched macromolecular structures. They are recognized to constitute the least controlled subset of structures in the major class of dendritic polymer architecture. In theory, all polymer-forming reactions can be utilized for the synthesis of hyperbranched polymers however, in practice some reactions are more suitable than others.
