This paper presents parallel computers architectures especially Superscalar
processors and Vector processors, building a simulator depending on the basic
characteristics for each architecture, the simulator simulates their mechanism of work
progra
mmatically at the aim of comparing the performance of the two architectures in
executing Data Level Parallelism (DLP) and Instruction Level Parallelism ILP.
The results shows that the effectiveness of executing instructions in parallel depends
significantly on choosing the appropriate architecture for execution, according to the type
of parallelism that can be applied to instructions, and the vector features in the vector
architecture achieve remarkable improvement in performance that cannot be ignored in
execution of DLP, simplify the code and reduce the number of instruction. The provided
simulator is a good core that can be developed and modified especially in the field of
education for the students of Computer Science and Engineering and the research field.
Indubitably, elements constituting the syntactic structure are one of the significant linguistic features of the symmetrical discourse in the linguistic order whether poetry or prose; since the symmetry discourse consists of two, or more, adjacent li
nguistic series.
However, the symmetrical discourse is one form of syntactic arrangements, as appears in organizing the text, and dividing it into similar constituents that soon bring forward a recognizable rhythmical dimension, which becomes clear in how long or short the tone is, whether this symmetrical discourse is full or partial, divided into longer stretches, or shorter ones interconnected by the conjunction 'and'.
No doubt that such a type of linguistic discourse, which divides the text into similar segments, acquires it harmony and cadence apparently missing in any other linguistic structure.
