FPGA is widely applied in datapath applications, so it's all important design issue to contrive FPGA architecture fit for datapath circuit implementation. In this paper, we described a new FPGA architecture -- FDEGA (Field-programmable Datapath Enhanced Gate Array). the LC of FDEGA is optimized for datapath implementation. and can be programmed as either combinational or sequential device. FDEGA has hierarchical interconnection architecture. A chip with 16*16 LC array has been fabricated, and the design of LC and interconnection has been tested, and circuit sample chosen from practical digital system design has been implemented in FDEGA. the result proves that our design of FDEGA is correct.

Withthe development of reconfigurable computers containing FPGAs with in excess of 6 million system-gates, it is now feasible to consider the possibility of sharing the FPGA between multiple concurrently executing applications. this could potentially increase the resource usage of the expensive FPGA logic and decrease response times so users will not have to wait for the FPGA to be completely available. However the system environment software required to support this, may actually result in application performance much less than would be considered acceptable to many FPGA users. this paper involves using a prototype to evaluate the performance of such an operating system, ReconfigME.

the hardware design and FPGA implementation of a voltage regulation control unit for optical phased array beam deflector is described. Withthe control unit used for a 16-channel waveguide phased array beam deflector, a beam scan rate above 500 kHz can be achieved, which is far higher than that obtained with other implementation methods based on microcontrollers.

this paper presents a 512-bit low power electrically programmable embedded non-volatile memory (eNVM) for the Internet of things (IoT) applications. A novel memory bit cell which is fully compatible to the CMOS logic process is developed using dual tunneling gate structure. Costumer designed lateral double diffused MOS transistor (LDMOS) is proposed in a novel high voltage management circuit to improve the reliability and safety of the memory established by thin gate oxide transistors. In charge pump design, a frequency step-up scheme is proposed to control the current surge during writing operation, thus large voltage droops in the power supply is prevented, improving the stability of the system. the memory is implemented in a standard 0.13 mu m CMOS technology process. Measured results indicate that under the supply voltage of 1.2 V, it consumes 9.2 mu W (22.9 mu W) at the read (write) rate of 6.78 Mb/s (8 kb/s). Endurance characteristics under 100k program cycles stress test and data retention characteristics of up to 10 years are demonstrated.
Rapid prototyping and simulation of digital systems using arrays of field programmable gate array (FPGA) chips is expected to be an important aspect of digital design and implementation. Four classes of architectures ...
