The field programmable gate array (FPGA) technology provides programmable system-on-chip (PSoC) environments for designing modern digital ASIC controllers for specific applications. This paper presents a FPGA based speed control IC for three-phase induction motor drives. The sinusoidal PWM is realized on a single FPGA chip from Xilinx Inc. to provide controlling switching pulses for inverter bl...

It is well known that Field Programmable Gate Arrays (FPGAs) can be used to accelerate calculations that take too much time on a Central Processing Unit (CPU). Methodologies have been proposed to reconfigure the FPGA at run time, depending on the needs of the system. The CPU and FPGA generally communicate through message passing, letting the programmer decide exactly which data needs to be pass...

FPGAs (Field-Programmable Gate Arrays) have been widely used as coprocessors to boost the performance of data-intensive applications [1][2]. However, there are several challenges to further boost FPGA performance: the communication overhead between the host workstation and the FPGAs can be substantial; large-scale applications cannot fit in a single FPGA because of its limited capacity; mapping...

This paper presents an intellectual property (IP) protection authentication scheme for field programmable gate array (FPGA) with embedded watermark. The use of digital watermarks to provide ownership (watermarking) and recipient (fingerprinting) identification for IP has become widespread. However, it could not prevent the unauthorized reuses when a person resells the watermarked FPGA design wi...

In 2000, the first high speed SiGe FPGA utilizing Current Mode Logic (CML) was proposed. The excellent high speed performance that CML allows made it a good candidate for use in high speed FPGA design. However, the large power consumption associated with CML (108mW for the FPGA building block) made the design difficult to scale up. To alleviate this problem, an improved FPGA with shorter propag...
