In view of the large and high real-time data transmission in the current strapdown INS, USB interface was integrated into the strapdown INS, and a strapdown inertial navigation real-time data processing system composed of the DSP, FPGA and the USB interface was designed. The system composition and working principle were described; the overall hardware design and software design of the system were...
We propose a new way to save energy in adaptive processors. According to an execution context the custom instruction set of an adaptive processor is selectively 'muted' at run time and thus the energy efficiency is significantly increased. Implemented are multiple so-called 'muting modes' each leading to particular leakage energy savings. A key challenge of this work is to determine which of the muting...
Following the synthesis and expansion of airborne devices' functions and the requirement of miniaturization of size, the traditional analog IF signal receiving system shows large size, high power consummation and low stability. It is difficult to satisfy the requirement of modern communications. This system applies software radio design thought and implements all digital IF signal processing and 485...

In the system, TMS320DM642 is used as the kernel processor to finish the image's fusion arithmetic, storage and display. FPGA, which has the ability to control the logic of image capturing, is used as the assistive processor. The experiment shows that this technology can obtain color fusion image.
A novel rank order statistic calculation algorithm for OS CFAR is presented. OS CFAR gives improved performance in a multitarget environment as compared to CA CFAR. However, the computational requirements of sorting data arrays complicate its implementation. We present an algorithm to overcome this challenge by employing a rank order statistic finding algorithm coupled with the exploitation of parallelism...
A robot vision system is developed based on an intelligent image gathering card that contains an FPGA (Field Programmable Gate Array) and a DSP (Digital Signal Processor) as main calculators.

Iris Identification is nowadays one of the most promising techniques in Authentication. Most modern iris recognition systems are currently deployed on traditional sequential digital systems, such as a simple DSPs or MIPS processor. However, in this method, we can only match each data one by one, which will waste much time. In this study, iris matching, a repeatedly executed portion of a modern iris...
Fast Fourier transform (FFT) is an essential component in many digital signal processing and communications systems. The performance of the FFT component is a key factor in evaluating the overall system performance, and it is common to use it as a benchmark for the whole system. Many attempts have been made to enhance the FFT performance, both on algorithm and implementation levels. Software and hardware...
To meet the complex requirements of the miniature embedded integrated (INS/GPS) navigation system based on DSP, all peripheral circuits were integrated in single chip of FPGA, such as logic control module, serial/parallel data conversion and FIFO(First In First Out), etc. The multi-channel UART(Universal Asynchronous Receiver Transmitter) consists of the data conversion circuit and FIFO. In addition,...
Most existing approaches to targeting high-level software to FPGAs are based on extensions to C and do not map easily to the features and characteristics of modern FPGAs. These include massive parallelism and a variety of complex IP-blocks (eg. RAMs, DSPs). In this paper we discuss a hardware implementation of SR, a software language with first class concurrency and high-level IPC.We show that the...
Smart cameras are becoming more popular in human computer interaction (HCI).
