The first point is when the average interconnect delay exceeds the gate delay, which happened during mid 1990s and led to the so-called timing closure problem. The second point is when single-cycle full chip synchronization is no longer possible, which is about to happen soon. It can be shown that, even with the aggressive interconnect optimization techniques (e.g., buffer insertion and wire-sizing), 5 clock cycles are still needed to go from corner-to-corner for the die of 28.3 mm /spl times/ 28.3 mm in the 0.07 /spl mu/m technology generation, assuming a 5.63 GHz clock by 2006 predicted in ITRS'01 (2001). This clearly suggests that multi-cycle on-chip communication is a necessity in multi-gigahertz synchronous designs. However, it is not supported in the current design tools and methodologies, as most of these implicitly assume that full chip synchronization in a single clock cycle is feasible. Our contributions are as follows: (i) we propose a regular distributed register (RDR) microarchitecture which offers high regularity and direct support of multi-cycle communication; (ii) we develop a set of novel architectural synthesis algorithms to efficiently synthesize behavior-level designs onto the RDR architecture.","PeriodicalId":174422,"journal":{"name":"First IEEE/ACM/IFIP International Conference on Hardware/ Software Codesign and Systems Synthesis (IEEE Cat.

While increasing complexity of the architectures demands high performance simulation, the increasing variety of available architectures makes retargetability a critical feature of an instruction-set simulator. Retargetability requires generic models while high performance demands target specific customizations. To address these contradictory requirements, we have developed a generic instruction model and a generic decode algorithm that facilitates easy and efficient retargetability of the ISA-simulator for a wide range of processor architectures such as RISC, CISC, VLIW and variable length instruction set processors. The instruction model is used to generate compact and easy to debug instruction descriptions that are very similar to that of architecture manual. These descriptions are used to generate high performance simulators. The generation of the simulator is completely separate from the simulation engine. Hence, we can incorporate any fast simulation technique in our retargetable framework without losing performance. We illustrate the retargetability of our approach using two popular, yet different realistic architectures: the Sparc and the ARM.","PeriodicalId":174422,"journal":{"name":"First IEEE/ACM/IFIP International Conference on Hardware/ Software Codesign and Systems Synthesis (IEEE Cat.

However the unpredictable dynamic behavior of caches makes schedulability analysis of such systems difficult. In particular, the effect of caches needs to be considered for estimating the inter-task interference. As the memory blocks of different tasks can map to the same cache blocks, preemption of a task may introduce additional cache misses. The time penalty introduced by these misses is called the cache-related preemption delay (CRPD). In this paper, we provide a program path analysis technique to estimate CRPD. Our technique performs path analysis of both the preempted and the preempting tasks. Furthermore, we improve the accuracy of the analysis by estimating the possible states of the entire cache at each possible preemption point rather than estimating the states of each cache block independently. To avoid incurring high space requirements, the cache states can be maintained symbolically as a binary decision diagram. Experimental results indicate that we obtain tight CRPD estimates for realistic benchmarks.","PeriodicalId":174422,"journal":{"name":"First IEEE/ACM/IFIP International Conference on Hardware/ Software Codesign and Systems Synthesis (IEEE Cat.
