An Approach to Manage Reconfigurations and Reduce Area Cost in Hard Real-Time Reconfigurable Systems
This article presents a methodology to build real-time reconfigurable systems that ensure that all the temporal constraints of a set of applications are met, while optimizing the utilization of the available reconfigurable resources. Starting fr[...]texto impreso
Olivito, Javier ; Serrano, Felipe ; Clemente Barreira, Juan Antonio ; Mecha, Hortensia ; Resano, Javier | Institution of Engineering and Technology | 2018-01-16In this paper we have evaluated the overhead and the tradeoffs of a set of components usually included in a system with run-time partial reconfiguration implemented on a Xilinx Virtex-5. Our analysis shows the benefits of including a scratchpad [...]texto impreso
Clemente Barreira, Juan Antonio ; Pérez Ramo, Elena ; Resano, Javier ; Mozos Muñoz, Daniel ; Catthoor, Francky | IEEE | 2014-06In spite of the increasing success of reconfigurable hardware, the dynamic reconfiguration can introduce important overheads, both in terms of energy consumption and time, especially when configurations are fetched from an external memory. In or[...]texto impreso
Clemente Barreira, Juan Antonio ; Gran, Rubén ; Chocano Gómez, Abel ; Prado, Carlos del ; Resano, Javier | IEEE | 2015-04-16The efficiency of the reconfiguration process in modern FPGAs can improve drastically if an on-chip configuration memory is included in the system because it can reduce both the reconfiguration latency and its energy consumption. However, FPGA o[...]texto impreso
Clemente Barreira, Juan Antonio ; Resano, Javier ; González Calvo, Carlos ; Mozos Muñoz, Daniel | IEEE | 2011-07New generation embedded systems demand high performance, efficiency and flexibility. Reconfigurable hardware can provide all these features. However the costly reconfiguration process and the lack of management support have prevented a broader u[...]texto impreso
Clemente Barreira, Juan Antonio ; González, Carlos ; Resano, Javier ; Mozos Muñoz, Daniel | 2008-12-30Reconfigurable hardware can be used to build a multitasking system where tasks are assigned to HW resources at run-time according to the requirements of the running applications. These tasks are frequently represented as direct acyclic graphs an[...]texto impreso
Resano, Javier ; Clemente Barreira, Juan Antonio ; González, Carlos ; García, José Luis ; Mozos Muñoz, Daniel | 2007Reconfigurable HW can be used to build a hardware multitasking system where tasks can be assigned to the reconfigurable HW at run-time according to the requirements of the running applications. Normally the execution in this kind of systems is c[...]texto impreso
Clemente Barreira, Juan Antonio ; Mozos Muñoz, Daniel ; Resano, Javier | 2011-09-01Dynamically reconfigurable hardware is a promising technology that combines in the same device both the high performance and the flexibility that many recent applications demand. However, one of its main drawbacks is the reconfiguration overhead[...]texto impreso
Clemente Barreira, Juan Antonio ; González Calvo, Carlos ; Resano, Javier ; Mozos Muñoz, Daniel | Elsevier | 2010-03Reconfigurable hardware can be used to build multi tasking systems that dynamically adapt themselves to the requirements of the running applications. This is especially useful in embedded systems, since the available resources are very limited a[...]
