While suppliers of digital signal processing (DSP) chips and programmable logic may differ over which device type is pre-eminent for new wireless system designs, what is important is what customers are actually implementing. Today, designers are applying a mix of both PLDs and DSP chips to meet market demand. The “intelligent partitioning” between these two device types gives wireless systems t...

This paper reports on design issues involved in combining two public-domain paradigms to create a parallel software environment for DSP programming. MPI (Message-Passing Interface), a message passing system, is an evolving standard for parallel computing. Khoros is an integrated software environment for DSP. The goal of this work is to describe and demonstrate a software design that exploits Kh...

Modem DSP Processors have been integrated with InsrrucrionLevel Purullelism(ILP), which presents a challenge to exploit ILP within DSP applications. Software Pipelining is an efficient tcchnique used to expose ILP for loop programs and has been widely used for current microprocessors. It has been recently used in DSP compilers, but only for the innermost loops. This paper proposes a new approac...

To aid risk assessment, management, and treatment planning it is essential to assess child sexual abusers' deviant sexual interests (DSI) and preferences (DSP) for sex with children. However, measurement of DSI/DSP is fraught with psychometric problems. In consequence, research interest has shifted to latency-based indirect measures as a measurement approach to complement self-report and physio...

Arti cial Neural Networks (NNs) are high parallel structures that consist of a large number of elementary non-linear units (called neurons) fully interconnected. In this article we present a hardware implementation of NNs combined with a DSP; both NNs and DSP combined together results in a powerful system used in control applications. NNs process most of the control tasks, while DSP performs si...

This paper presents digital speed control of permanent magnet brushless dc motor using TMS320F2812 DSP controller. The DSP controller used here has the special features for digital motor control. Control algorithms used for the speed control has been implemented by assembly language programming in TMS320F2812 DSP controller. According to the input command, feedback and the control algorithm, th...

This application note discusses various design techniques for implementing resampling filters using the Altera® DSP Builder advanced blockset. The DSP Builder advanced blockset supports constraint-based high-level synthesis and is particularly efficient for implementing multiple channel, high-performance resampling filters. You can use the DSP Builder advanced blockset to quickly map highly abs...

To construct complete systems on silicon, application specific DSP accelerators are needed to speed up the execution of high throughput DSP algorithms. In this paper, a methodology is presented to synthesize high throughput DSP functions into accelerator processors containing a datapath of highly pipelined, bit-parallel hardware units. Emphasis will be put on the definition of a controller arch...

{ This paper presents the machine description language LISA for the generation of bit-and cycle accurate models of DSP processors. Based on a behavioral operation description, the architectural details and pipeline operations of modern DSP processors can be covered. Beyond the behavioral model, LISA descriptions include other architecture-related information like the instruction set. The inform...
