CODE OPTIMIZATION METHOD FOR QUALCOMM HEXAGON PROCESSOR, SUPPORTING INSTRUCTION LEVEL PARALLELISM AND BUILT WITH VLIW (Very Long Instruction Word) ARCHITECTURE

A method for optimizing the filling of a machine word with independent instructions is proposed, which allows to increase the performance of programs by stacking the maximum number of independent commands in a package. The paper also confirms the hypothesis that with the transition to random register allocation by the compiler, the packet density will increase, which will result in a decrease in the program's running time.

2-Quasitotal Fuzzy Graphs and Their Total Coloring

Coloring of fuzzy graphs has many real-life applications in combinatorial optimization problems like traffic light system, exam scheduling, and register allocation. The coloring of total fuzzy graphs and its applications are well studied. This manuscript discusses the description of 2-quasitotal graph for fuzzy graphs. The proposed concept of 2-quasitotal fuzzy graph is explicated by several numerical examples. Moreover, some theorems related to the properties of 2-quasitotal fuzzy graphs are stated and proved. The results of these theorems are compared with the results obtained from total fuzzy graphs and 1-quasitotal fuzzy graphs. Furthermore, it defines 2-quasitotal coloring of fuzzy total graphs and which is justified.

About the Study of the Means of Transcription of Works for Clavier by Beginning Pianists

The methodological elaborations of the rubric of the journal “My fi rst transcriptions” will present examples from assignments from the attempts of creative work of beginning pianists with the musical text. The offered assignments carry the aim of teaching certain universal techniques of artistic transformation of the composer’s primary text. The fi rst article devoted to this subject matter examines the register allocation and the doubling which were applied in everyday music-making in the 16th and 17th centuries during the varied re-exposition of the clavier text into various ensembles. The technique of their application is simple and accessible to contemporary listeners as well; it presumes the utilization of timbral possibilities of the present-day piano and keyboard synthesizer. At the basis of the elaboration of the assignments there are fragments of J.S. Bach’s instructive compositions from such compilations as “Kleinen Preludien und Fugen,” “Klavierbüchlein für Wilhelm Friedemann Bach,” as well as the “French Suites,” all of which assume a transformation of the clavier text for performing it in various variants and instrumental ensembles. These are the introductory pieces to the cycles: the preludes, fantasies or the pieces in the dance genres.The lessons are organized in the piano classes upon the conditions of “sight-reading” either in a solo manner, or with participation of partners in the form of intonational etudes. The analysis of the semantic structures applies role playing games in the subject matter of “I am playing the organ,” “there is a rehearsal of a historical orchestra going on,” “Trio for two fl utes and cello,” etc.
