The inherent reconfigurability of FPGAs enables us to optimize an FPGA implementation in different time intervals by generating new optimized FPGA configurations and reconfiguring the FPGA at the interval boundaries. With conventional methods, generating a configuration at run-time requires an unacceptable amount of resources. In this paper, we describe a(More)
Parameterised reconfiguration is a method for dynamic circuit specialization on FPGAs. The main advantage of this new concept is the high resource efficiency. Additionally, there is an automated tool flow, TMAP, that converts a hardware design into a more resource-efficient run-time reconfigurable design without a large design effort. We will start by(More)
Dynamic hardware generation is a powerful technique that can substantially reduce both the required hardware resources and the time needed to perform a calculation, reflected in an improved functional density. This performance improvement is a result of additional run-time optimizations enabled by the knowledge of values at certain inputs at runtime.(More)
Fine grained Field Programmable Gate Arrays (FPGA) are complex to program and therefore suffer from high development costs. To solve this problem, Virtual Coarse Grained Reconfigurable Arrays (Virtual CGRA), or CGRAs implemented on FPGAs, have been proposed. Conventional implementations of VCGRAs use functional FPGA resources, such as LookUp Tables, to(More)
The FASTER project aims to ease the definition, implementation and use of dynamically changing hardware systems. Our motivation stems from the promise reconfigurable systems hold for achieving better performance and extending product functionality and lifetime via the addition of new features that work at hardware speed. This is a clear advantage over the(More)
In many applications, subsequent data manipulations differ only in a small set of parameter values. Because of their reconfigurability, FPGAs (field programmable gate arrays) can be configured with an optimized configuration every time the parameter values change. These optimized configurations are smaller and faster than their generic counterparts.(More)
In many applications, subsequent data manipulations differ only in a small set of parameter values. Because of their reconfigurability, FPGAs (field programmable gate arrays) can be configured with a specialized circuit each time the parameter values change. This technique is called dynamic data folding. The specialized circuits are smaller and faster than(More)
In many applications, subsequent tasks differ only in a specific set of parameters. Because of their reconfigurability, FPGAs (field programmable gate arrays) can be configured with an optimized configuration every time these parameter values change. This results in configurations that are smaller and faster than their generic counterparts. Unfortunately,(More)
Dynamic partial reconfiguration of FPGAs enables the dynamic specialization of the circuit for the runtime needs of the application. Previously a tool flow, called the TLUT tool flow, was developed to aid the designer in applying dynamic circuit specialization (DCS) for their designs. The TLUT tool flow generates an implementation in which the lookup tables(More)
