This paper presents a novel micro-architecture for high-performance and low-power DSPs. The underlying Synchronous Transfer Architecture (STA) fills the gap between SIMD-DSPs and coarse-grain reconfigurable hardware. STA processors are modeled using a common machine description suitable for both compiler and core generator. The core generator is able to(More)
Recently, digital signal processors featuring vector SIMD instructions have gained renewed attention, since they offer the potential to speed up the computation of digital signal processing algorithms. However, when implementing recursive algorithms the maximum achievable speed-up factors are upper bounded. In this paper, we investigate these performance(More)
This paper presents an adaptation of the list scheduling algorithm to generate code for processors of the Synchronous Transfer Architecture (STA) by applying techniques known from RISC and TTA. The proposed scheduling approach is based on informed, deterministic algorithms that can be implemented run-time efficiently. Although the presented compiler(More)
SIMD processors have made their way from supercomputers architectures through embedded real-time signal processing. This trend has been driven by signal processing applications with heavy number-crunching requirements like for example base-band processing on mobile devices. Depending on the data dependencies of algorithms and implementation constraints like(More)
This paper presents a novel processor architecture tailored to the efficient execution of digital signal processing algorithms efficiently that are developed using the Matlab programming language. Based on the synchronous transfer architecture (STA) and SIMD processing the goal of the architecture is the minimization of the overhead associated with(More)
Driven by the ever increasing algorithm complexity on the field of mobile communications systems, SIMD DSP architectures have emerged as an approach that offers the necessary processing power at reasonable levels of die size and power consumption. However, this kind of DSP architectures imposes new challenges for programmers, since algorithms have to be(More)
With the approaching 3G wireless standard, the development of an efficient technique for transporting a mix of voice and data over limited bandwidth links is crucial. State of the art GSM systems use the connection oriented ATM protocol, while data networking is based on the best-effort IP protocol. ATM protocols have been developed for efficient universal(More)
Terrestrial digital video broadcasting (DVB-T) is currently being introduced in many European countries and planned to supplement or replace current analogue broadcasting schemes in a large part of the world. It is also considered as an additional downlink medium for third generation UMTS mobile telephones, where a special variant, DVB-H, is under(More)
