Digital signal processing (DSP) occurs in communications, audio, multimedia devices, imaging and medical equipment, smart antennas, automotive electronics, MP3 players, radar and sonar, and barcode readers. This algorithm can be implemented in Microsemi® system-on-chip (SoC) Products Group flash based field programmable gate array (FPGA), mixed signals FPGA, and also radiation-tolerant FPGA. Th...

The ongoing advances in semiconductor technology are the enabler for complete System on Chip (SoC) solutions. In this SoC domain Digital Signal Processors (DSPs) are employed to carry out software driven digital signal processing tasks. Although DSPs could still be modified in the SoC domain, they are mainly employed as fixed DSP cores. Possible adaptations to the embedding system cannot be car...

AIMS Diagnosis of early distal symmetric polyneuropathy (DSP) is challenging. Nerve conduction studies (NCS) are often normal. Skin biopsy for intraepidermal nerve fiber density (IENFD) has better sensitivity, but is invasive. Sudoscan is a novel technology that measures electrochemical skin conductance (ESC; microSiemens, μS), which is thought to be proportionate to the number of functional sw...

This paper proposes a parameterized digital signal processor (DSP) core for an embedded digital signal processing system designed to achieve demodulation/synchronization with better performance and flexibility. The features of this DSP core include parameterized data path, dual MAC unit, subword MAC, and optional function-specific blocks for accelerating communication system modulation operatio...

This paper describes a high-performance scalable SIMD digital signal processor (DSP) developed for multifunctional printer systems. The DSP supports a variable number of datapaths to cover a wide range of performance and maintain a RISC-like pipeline structure. Many special instructions suitable for image processing algorithms are included in the DSP. Quad/dual instructions are introduced for 8...

The number and variety of products that include some form of digital signal processing has grown dramatically over the last five years. DSP has become a key component in many consumer, communications, medical, and industrial products. These products use a variety of hardware approaches to implement DSP, ranging from the use of off-the-shelf microprocessors to field-programmable gate arrays (FPG...

DSP-128 is a new multithreaded stream cipher based on the intractability of the Discrete Logarithm Problem (DLP) with key size of 128-bit. The design of DSP-128 is divided into three stages: Initialization Stage, Keystream Generation Stage, and Encryption Stage. The design goal of DSP-128 is to come up with a secure stream cipher with good performance for data encryption. The experimental resul...

Today's DSP designers until recently were faced with the task of coding increasingly complex applications using inefficient compilers or tedious handgenerated assembly code. To make matters worse the products demanded low cost, extremely high performance and low power especially in the area of wireless communications and consumer markets. This paper examines the architectural features of severa...

This paper presents the hardware design of a real time tracking system based on DSP/FPGA regarding the research and development of a certain type of short range defence radar. In this tracking system, the FPGA is used as a floating point co-processor of the fixed point DSP, and the large amount of calculation of the debiased converted measurement Kalman Filter (DCMKF) algorithm is realized in F...

In this paper, we present a basic model for describing hardand software of heterogeneous multi-DSP systems. The software part consists of a task model that has been tuned to suit typical, cyclic DSP applications. Hardware is described by a processor model adapted to multi-DSP systems with point-to-point communication structure, which also includes an exact model of communication timing behavior...
