| - | * Abstract: As the number of system gates available on reconfigurable platforms increase beyond 20 million, the issue of the management of these resources and their sharing among may applications and users will become more of a concern. In this paper we describe the research issues for managing these resources in an operating system for a reconfigurable computer. We also detail a feasible set of components for the operating system and a feasible software architecture We show there is no current operating system implementation with these components. We propose a number of performance metrics which we believe are important measures of the quality of an operating system implementation. These include fragmentation of area, algorithm performance and application performance. We complete the paper with a status report on our implementation of an operating system for a reconfigurable computer. | + | |

| - | * Abstract: Reconfigurable computing applications have traditionally had the exclusive use of the field programmable gate array, primarily because the logic densities of the available devices have been relatively similar in size compared to the application. But with the modern FPGA expanding beyond 10 million system gates, and through the use of dynamic reconfiguration, it has become feasible for several applications to share a single high density device. However, developing applications that share a device is difficult as the current design flow assumes the exclusive use of the FPGA resources. As a consequence, the designer must ensure that resources have been allocated for all possible combinations of loaded applications at design time. If the sequence of application loading and unloading is not known in advance, all resource allocation cannot be performed at design time because the availability of resources changes dynamically. In this paper, we present an implementation of an operating system that has the ability to share its FPGA resources dynamically among multiple executing applications. | + | |

| - | * Authors: Klaus Danne | + | |

| - | * Abstract: We introduce the concept of an operating system for platforms that consist beside memory and peripheral devices of FPGAs as the only computational resource. Applications can be developed independent from each other and due to device drivers with little dependency on the platform. The OS supports the multitasking execution of applications using static as well as dynamic resource assignment. A main focus of the paper is the management of the resource memory. Memory management as part of the OS is introduced which allows multiple tasks to access the same memory banks using virtual addressing and dynamic memory allocation. Access conflicts are solved by a priority based scheduling. Since no microprocessor is part of the system, the entire OS including its memory management is executed on the FPGAs. | + | |

| - | * Abstract: Self-reconfigurable hardware is a new emerging technology which will enable adaptation of computing systems to changing environments.This paper deals with the design of architecture kernels for an autonomous on-board system and the development of an adaptation manager for real-time scheduling of the reconfigurable hardware fabric.Our approach employs a reconfigurable computer architecture with two key layers: the adaptation manager and the real time configuration kernel. This provides significant advantages in terms of flexibility, scalability, cost, and compatibility with embedded technology. Some preliminary results are presented. | + | |

| - | ** Description: Podazajac tropem Piotrka natrafilem na ciakawy artykul (w zalaczniku) prezentujacy opracowany w Berkeley system operacyjny (rozszerzenie UINX'a) dla architektur opartych o FPGA. Artykul jest dosc "swiezy" bo z 2006 roku. Co wiecej, w Transactions on Embedded Computing Systems 2008 znalazlem artykul tych samych autorow, o tym samym tytule (niestety, nie udalo mi sie dotrzec do jego tresci). Zasadnicza czesc proponowanego systemu pracuje na procesorze PowerPC znajdujacym sie w glownym FPGA. Oprocz glownego FPGA sa jeszcze 4 uklady "user FPGA", w ktorych realizowane sa zadania uzytkownika. Osiagnieciem autorow jest ujednolicenie obslugi zadan implementowanych sprzetowo i programowo. Choc glowna koncepcja przedstawiona w artykule znacznie rozni sie od naszego pomyslu to warto go przeczytac ze wzgledu na prezentowane w nim mechanizmy komunikacji miedzy zadaniami i dostepu do pamieci. Lekture polecam szczegolnie naszym informatykom. Jak widac z artykulu, odpowiednia architektura sprzetu moze znacznie przyspieszyc prace systemu operacyjnego. Mocna strona artykulu jest to, ze nie przedstawia on jedynie luznych koncepcji ale konkretne, sprawdzone rozwiazania. | + | |

| - | ** Description: Po krotce mowiac, praca dotyczy opracowania narzedzi i metodologii (COMMA design flow opartej na Early Access Partial Reconfiguration Tool Flow) wspierajacych synteze ukladow wykorzystujacych modulowa rekonfiguracje dynamiczna na wspoczesne uklady rekonfigurowalne XILINX'a (rodzina Spartan-4) i jednoczesnie wspolpracujace z dostepnymi narzedziami producenta. Glowny nacisk w pracy polozony zostal na generacje i optymalizacje polaczen pomiedzy modulami dynamicznie rekonfigurowalnymi. Zaproponowane podejscie umozliwia zachowanie takich paramterow projektu jak np. ograniczenia czasowe, przy jednoczesnym spadku czasu dynamicznej rekonfiguracji do okolo 64% (w porownaniu do zastosowania dostepnych komercyjnie narzedzi). Autor w pracy implementuje model Brebnera ("fixed wiring harness" model), a tazke algorytm greedy'ego do łączenia grafow wsparte, rozwiniete czy tez nawet zastapione przez metode dynamicznego programowania. | + | |

| - | ** Description: The tree SSA project requires a tree representation of functions for the optimizers to operate on. There was an existing functions-as-trees representation shared by the C and C++ front ends, and another used by the Java front end, but neither was adequate for use in optimization. In this paper, we will discuss the design of GENERIC, the new language-independent tree representation, and GIMPLE, the reduced subset used during optimization. | + | |
