This paper discusses the use of partial reconfigurability in Xilinx FPGA designs in order to aid debugging. A debugging framework is proposed where the use of partial reconfigurability can allow for added flexibility by allowing a debugger to decide at run time what debugging module to use. This paper also presents an open source debugging tool which allows a user to read-out the contents of memory...
In this paper we discuss how various design components perform in both FPGAs and standard cell based ASICs. We also investigate how various common FPGA optimizations will effect the performance and area of an ASIC port. We find that most techniques that are used to optimize a design for an FPGA will not have a negative impact on the area in an ASIC. The intended audience for this paper are engineers...
As the use of FPGAs increases, the importance of highly optimized processors for FPGAs will increase. In this paper we present the microarchitecture of a soft microprocessor core optimized for the Virtex-4 architecture. The core can operate at 357 MHz, which is significantly faster than Xilinxpsila Microblaze architecture on the same FPGA. At this frequency it is necessary to keep the logic complexity...
There is increasing interest about floating-point arithmetics in field programmable gate arrays (FPGAs) because of the increase in their size and performance. FPGAs are generally good at bit manipulations and fixed-point arithmetics, but they have a harder time coping with floating-point arithmetics. An architecture used to construct high-performance floating-point components in a Virtex-4 FPGA is...
Networks on chip (NoC) has long been seen as a potential solution to the problems encountered when implementing large digital hardware designs. In this paper we describe an open source FPGA based NoC architecture with low area overhead, high throughput and low latency compared to other published works. The architecture has been optimized for Xilinx FPGAs and the NoC is capable of operating at a frequency...
