Superscalar processing is the latest in a long series of innovations aimed at producing everyaster microprocessors. By exploiting instruction-level parallelism, superscalar processors are capable of executing more than one instruction in a clock cycle. This paper discusses the microarchitecture of superscalar processors. We begin with a discussion of the general problem solved by superscalar pr...

Recent advances in graphics processing units (GPUs) have resulted in massively parallel hardware that is easily programmable and widely available in commodity desktop computer systems. GPUs typically use single-instruction, multiple-data (SIMD) pipelines to achieve high performance with minimal overhead for control hardware. Scalar threads running the same computing kernel are grouped together ...

2 of 41 Real-time Signal Processing on the Ultrasparc 1.0 Abstract With the convergence of audio, video, and the Internet, multimedia applications increasingly demand real-time processing from general purpose CPUs. Traditionally, computer architects have increased the performance of CPUs in incremental steps, increasing the number of cache levels, increasing the complexity of I/O controllers, i...

Contemporary computing architectures make an extensive use of cache memories to cope with the increasing speed gap between the processing power of the processing element and the bandwidth of the memory subsystem. In a fixed-priority preemptive real-time system, in addition to obtaining logically correct results, it is also mandatory to satisfy timing constraints. Since the contents of the cache...

As is known from psychometrics, restriction of task processing time by the instruction to respond as quickly and accurately as possible leads to task-unspecific cognitive processing. Since this task processing mode is used in most functional neuroimaging studies of human cognition, this may evoke cortical activity that is functionally not essential for the particular task under investigation. U...

To the present day, the performance of microprocessors has progressed dramatically. Recently, almost all computer systems use reduced instruction set computer (RISC) architectures. However, about 30 years ago, complex instruction set computer (CISC) architectures were widely used for almost all computer systems. The advantages and successes of RISC architectures are attributable to their simpli...

In this paper the author describes about superscalar processor and its architecture. A superscalar architecture is one in which several instructions can be initiated simultaneously and executed independently. pipelining allows several instructions to be executed at the same time, but they have to be in different pipeline stages at a given moment. Superscalar architectures include all features o...
