This paper provides quantitative measurements of load latency tolerance in a dynamically scheduled processor and presents one cache management technique that exploits this information to improve overall performance. We determine the latency of each memory load operation such that the number of instructions issued per cycle (IPC) is comparable to an ideal memory system that satisfies all request...

We study a variant of the capacitated vehicle routing problem where the cost over each arc is defined as the product of the arc length and the weight of the vehicle when it traverses that arc. We propose two new mixed integer linear programming formulations for the problem: an arc-load formulation and a set partitioning formulation based on q-routes with additional constraints. A family of cycl...

The Organic Rankine Cycle (ORC) has been proved a promising technique to exploit waste heat from Internal Combustion Engines (ICEs). Waste heat recovery systems have usually been designed based on engine rated working conditions, while engines often operate under part load conditions. Hence, it is quite important to analyze the off-design performance of ORC systems under different engine loads....

Heart sounds, the acoustic vibrations produced by the mechanical processes of the cardiac cycle, are modulated by respiratory activity. We have used computational techniques of cluster analysis and classification to study the effects of the respiratory phase and the respiratory resistive load on the temporal and morphological properties of the first (S1) and second heart sounds (S2), acquired f...

Tomasulo’s algorithm creates a dynamic execution order that extracts a high degree of instruction-level parallelism from a sequential program. Modern processors create this schedule early in the pipeline, before operand values have been computed, since present-day cycle-time demands preclude inclusion of a full ALU and bypass network delay in the instruction scheduling loop. Hence, modern sched...

Electric Vehicles (EVs) require energy storage system that can address its fast changing load requirements such as sudden acceleration or quick regenerative braking by being able to supply or absorb high power as demanded. Lead Acid Batteries, commonly used in cheaper EVs (like electric tempo in Nepal), can properly supply these variable loads and get recharged but this mode of operation drasti...

A transport equation residual model incorporating a Damkohler criterion has been developed and implemented in the ERC KIVA-3V code for Gasoline Direct Injection (GDI) engine simulations for better predictions of flame propagation. In the transport equation residual model a fictitious species concept is introduced to account for the residual gases in the cylinder, which have a great effect on th...

Multithreaded processors use a fast context switch to bridge latencies caused by memory accesses or by synchronization operations. In the block-multithreaded processor – called Rhamma – load/store, synchronization and execution operations of different threads of control are executed simultaneously by appropriate functional units. A fast context switch is performed, whenever a functional unit co...

An extension of the one-cycle control (OCC) method for switched-capacitor (SC) converters is proposed in this paper, featuring a fast dynamic response, wide line and load operation ranges, and simplicity in implementation. To illustrate the operation principle of this nonlinear control method and to demonstrate its simplicity in design, a dual-phase unity gain SC converter is examined. A new co...
