Control and data speculation are widely used to improve processor performance. Correct speculation can reduce execution time, but incorrect speculation can lead to increased execution time and greater energy consumption. This paper proposes a mechanism to leverage unexpected program behavior, called wrong-path events, that occur during periods of incorrect speculation. A wrong-path event is an ...

the ip lookup process is a key bottleneck in routing due to the increase in routing table size, increasing traıc and migration to ipv6 addresses. the ip address lookup involves computation of the longest prefix matching (lpm), which existing solutions such as bsd radix tries, scale poorly when traıc in the router increases or when employed for ipv6 address lookups. in this paper, we describe a ...

Recently, multicore processor and virtualization become popular in research and application. And an even newer tendency is to deploy virtualization on multicore processor platform. This means on a physical server, several isolated and high performance virtual environments are provided, and concurrent program has a chance to run in a multicore virtualized environment. But most virtual processor ...

As a program executes, some computations are performed over and over again. These redundant computations increase the program’s execution time since they require multiple cycles to execute and because they consume limited processor resources. To minimize the performance degradation that redundant computations have on the processor, we propose using Instruction Precomputation hardware to dynamic...

It is generally accepted that a custom hardware implementation of a set of computations will provide superior speed and energy-efficiency relative to a software implementation. However, the cost and difficulty of hardware design is often prohibitive, and consequently, a software approach is used for most applications. In this paper, we introduce a new high-level synthesis tool called LegUp that...

A process is an instance of a computer program that is being sequentially executed by a computer system that has the ability to run several computer programs concurrently. A computer program itself is just a passive collection of instructions, while a process is the actual execution of those instructions. Several processes may be associated with the same program; for example, opening up several...
