Digital Signal Processing (DSP) and multimedia workloads are expected to be the dominant workloads on future computer systems. This is true in both low cost embedded applications that use specialized microprocessors like DSPs and in the generalpurpose processor market. Very Long Instruction Word (VLIW) architectures have multiple functional units to take advantage of vastly available Instructio...

Recursive filters are used frequently in digital signal processing. They can be implemented in dedicated hardware or in software on a digital signal processor (DSP). Software solutions often are preferable for their speed of implementation and flexibility. However, contemporary DSPs are mostly not fast enough to perform filtering for high datarates or large filters. A method to increase the com...

This paper describes a software architecture for parallel real-time signal processing systems. The architecture consists of two layers: the engine layer, which performs real-time signal processing, and the host layer, responsible for control and configuration operations. Client programs access DSP resources through “objects,” which encapsulate physical resources, signal processing algorithms, a...

The key technology of the mobile multimedia application is System-On-Chip processor that integrates the major function unit with low power consumption using a small battery. The wireless communication is practical technology, which makes comfortable communications between devices, such as IEEE 802.11a/b/g and Bluetooth. By the modern streaming technology with compression, like mpeg, the wireles...

The DSPstone evaluation methodology is applied to evaluate performance of xed{ and oating{point digital signal (DSP), and general purpose (GPP) processors with appropriate C compilers. Main goal was to estimate run{ time e ciency on code which is representative for baseband processing in multimedia applications. The results show that for DSP{type code, like FIR ltering, DSP processors are super...

Work with the discrete sequence production (DSP) task has provided a substantial literature on discrete sequencing skill over the last decades. The purpose of the current article is to provide a comprehensive overview of this literature and of the theoretical progress that it has prompted. We start with a description of the DSP task and the phenomena that are typically observed with it. Then we...

This paper describes the design and implementation of a 16bit fixed point DSP processor. The processor is intended as a platform for hardware accelerators and allows additional computational units and assembler instructions to be added. The I/O facilities can also be customized to the needs of a specific application. Benchmarking has shown that the processor, without any hardware accelerators, ...

The speed of current PCs enables them to decode and play an MPEG bitstream in real time. The encoding process, however, cannot be done in real-time. The purpose of this thesis is to produce a low-cost real-time Digital Signal Processor (DSP) implementation of an MPEG encoder. The DSP will provide an MPEG bitstream to the PC that can be saved to disk. The input to the DSP will be an analog audio...

The thesis presents an implementation of a general DSP framework on the Texas Instruments OMAP-L138 processor. Today's software-defined radios suffer from fundamental drawbacks that inhibit their use in practical settings. These drawbacks include their large sizes, their dependence on a PC for digital signal processing operations, and their inability to process signals in real-time. Furthermore...
