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)
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)
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 a novel processor architecture tailored to the efficient execution of digital signal processing algorithms efficiently that are developed using the Matlab TM 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)
In this paper the low-power high-performance floating-point vector DSP (SAMIRA) is presented primarily intended for base-band signal processing applications. SAMIRA DSP is build upon 0.13mum UMC technology running at a maximum clock frequency of 212MHz. The processor combines SIMD and VLIW parallelism and it represents the first silicon prototype based on(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)
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)
Performance achievements on programmable architectures due to process technology are reaching their limits, since designs are becoming wire- and power-limited rather than device limited. Likewise, traditional exploitation of instruction level parallelism saturates as the conventional approach for designing wider issue machines leads to very expensive(More)
