— Facilities layout is a systematic and functional arrangement of different departments, machines, equipments and services in a manufacturing establishment. It is vitally important to have a well developed plant layout for all the available resources in an optimum manner and get the maximum out of the capacity of the facilities. The problem is of particular importance for Small and Medium Enter...

| Field-Programmable Gate Arrays (FPGAs) are now widely used for the implementation of digital systems and many commercial architectures are available. Although the literature and data books contain detailed descriptions of these architectures, there is very little information on how the high-level architecture was chosen and no information on the circuit-level or physical design of the devices...

We present an on-line algorithm for prefetching and caching for a multiple-disk parallel I/O system. We introduce the notion of write-back whereby blocks are relocated between disks during the course of the computation. Write-back allows the layout to be altered dynamically to suit access patterns in different parts of the reference string. The algorithm is analyzed using the standard parallel ...

As multimedia applications on mobile devices become more computationally demanding, embedded processors with one level I-cache become more prevalent, typically with a combined I-cache and SRAM of 32KB ~ 48KB total size. Code size reduction alone is no longer adequate for such applications since program sizes are much larger than the SRAM and I-cache combined. For such systems, a 3% I-cache miss...

The packing layout for loading boxes of identical format on a pallet can be determined algorithmically. This is important when performing automated packing by a robot. The well-known four-block heuristics and G4heuristics produce very efficient loading patters in most practical cases. In addition to the number of boxes on the pallet, one has to maximize the stability of the loading. This paper ...

Aiming at the production scheduling problem in the hull block production, this study investigates the maximum use of the assembly blocks working platform. By transforming the scheduling problem into two-dimensional bin packing problem, this study explores the effective block spatial layout under the condition of spatial constraints. In order to improve the drawbacks of the lowest horizontal lin...

We present Chopper, a tool that efficiently explores the vast input space of file system policies to find behaviors that lead to costly performance problems. We focus specifically on block allocation, as unexpected poor layouts can lead to high tail latencies. Our approach utilizes sophisticated statistical methodologies, based on Latin Hypercube Sampling (LHS) and sensitivity analysis, to expl...

A graphical environment for Computer-Aided Control System Design (CACSD) has been developed based on a hierarchical mouse-and-menu command structure which provides access to both in-house and commercially available design and analysis tools and packages through file-based interfaces. Facilities are provided for the input of system descriptions in either block diagram or signal flow graph form. ...

File systems treats Flash storage device as a traditional storage media with their logical address. However inside the Flash storage device, Flash Translation Layer (FTL) remaps logical address to physical address to hide physical limitation of Flash memory cells. Due to the address translation, intentional logical separation of file system’s layout does not directly applied to physical separat...
