At 400 MHz, this translates to a peak arithmetic rate of 16 GFLOPS on single-precision data and 32 GOPS on 16 bit fixed-point data. The scalability of Imagine's programming model and architecture enable it to achieve such high arithmetic rates. Imagine executes applications that have been mapped to the stream programming model. The stream model decomposes applications into a set of computation kernels that operate on data streams. This mapping exposes the inherent locality and parallelism in the application, and Imagine exploits the locality and parallelism to provide a scalable architecture that supports 48 ALUs on a single chip. This paper presents the Imagine architecture and programming model in the first half and explores the scalability of the Imagine architecture in the second half.","PeriodicalId":164768,"journal":{"name":"Proceedings.

Preloaded tagless loop caching supports complex loops with branches and thus can reduce power further, but has a limit on the total number of instructions cached. We show that each does well on particular benchmarks, but neither is best across all of those benchmarks. We present a new hybrid loop cache that only preloads the complex loops, while dynamically loading other loops, thus achieving the strengths of each approach. We demonstrate better power savings than either previous approach alone.","PeriodicalId":164768,"journal":{"name":"Proceedings.

The system, \"Media embedded Processor Integrator\", provides a distinctive feature that generates development tools, such as compilers and simulators, not only for the configurable embedded processor but also for its template based extensible VLIW co-processor. This paper describes the architecture and the function of the \"Media embedded Processor Integrator\" especially focusing on how the system treats the VLIW co-processor extension. In order to determine an ISA for a 3-way VLIW co-processor for image recognition as an example, several different sets of ISA were evaluated and compared for the best performance using corresponding compilers and simulators, which were generated by the system. The system greatly contributed to reduce this entire ISA definition process.","PeriodicalId":164768,"journal":{"name":"Proceedings.

The evaluation has three scopes ndividual components on SN nodes (processor, communication, storage, sensors, actuators, and power supply), node level and networked system level. The special emphasis is placed on architecture and system software, and on new challenges related to the usage of new types of components in networked systems. The evaluation is guided by anticipated technology trends and both current and future applications. The main conclusion of the analysis is that the architectural and synthesis emphasis will be shifted from computation and to some extent communication components to sensors and actuators.","PeriodicalId":164768,"journal":{"name":"Proceedings.

Our predictor reduces branch prediction power dissipation by selectively turning on and off two of the three tables used in the combined branch predictor BPP relies on a small buffer that stores the addresses and the sub-predictors used by the most recent branches executed. Later we refer to this buffer to decide if any of the sub-predictors and the selector could be gated without harming performance. In this paper we study power and performance trade-offs for a subset of SPEC 2k benchmarks. We show that on the average and for an 8-way processor, BPP can reduce branch prediction power dissipation by 28% and 14% compared to non-banked and banked 32k predictors respectively. This comes with a negligible impact on performance (1% max). We show that BPP always reduces power even for smaller predictors and that it offers better overall power and performance compared to simpler predictors.","PeriodicalId":164768,"journal":{"name":"Proceedings.

We present a general sufficient condition for register binding to ensure that a given set of functional units is PPM. This condition not only applies to data-flow intensive (DFI) behaviors but also to control-flow intensive (CFI) behaviors. It leads to a straightforward power-managed (PM) register binding algorithm. The proposed algorithm is independent of the functional unit binding and scheduling algorithms. Hence, it can be easily incorporated into existing high-level synthesis systems. For the benchmarks we experimented with, an average 45.9% power reduction was achieved by our method at the cost of 7.7% average area overhead, compared to power-optimized register-transfer level (RTL) circuits which did not use PM register binding.","PeriodicalId":164768,"journal":{"name":"Proceedings.
