To avoid this problem, a method based on fine-grained control for integration of FPU into the RISC processor is proposed in this paper. In terms of operand width of floating-point instructions, the method divides floating instructions into three categories: S, D and U, and further subdivides the execution status of S, D and U. Then, it regards the execution status as basic granularity to generate the FPU control information and moves the control information needed by destination operands to the next pipeline stage. Finally, segmentation of destination operands is achieved in different pipeline stages and the destination operand is written to register file after segmentation with the pipeline. An 80-bit FPU is embedded into a SPARC V8 processor based on the proposed method. The results of implementation and verification show that the critical path of floating instructions decreases by 37.3%, hardware consumption reduces by 16.9% and the floating-point calculation efficiency increases 1.7 times. The proposed method can be used to apply the ultra-precision FPU embedded into the RISC processor, and to make an efficient collaborative computing between them at low hardware overheads.","PeriodicalId":153592,"journal":{"name":"The Open Automation and Control Systems Journal","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115106135","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Research Questions: 1. Does the control loops model with the cubic characteristic equation leads the to the relatively simple conditions for ensuring aperiodic transients? 2. Does the simple terms derived by approximate formula for Q-factor in line with the terms of oscillability lack by using the certain inequality, which is correct for the cubic equation with the real roots only? 3. Does the simple regulators good in overdamping the transition oscillations? 4. Does the conditions for ensuring aperiodic transients in automatic control systems helpful for the quick robust PID tuning? Literature Review: The purpose of the literature review was to provide a brief historical background of the research task. The key research results are achieved in the quasi-optimal PID tuning field. The attempts of synthesis the relatively simple PID tunung analytical methods was undertaken for partial narrow tasks. Methodology: The case study is based on the qualitative analysis of cubic control loops characteristic equation. The results of qualitative analysis proved by the LabView simulation using the Control Design and Simulation Module. Results and Conclusions: Several examples of oscillation transients occurs at automatic control systems described by a mathematical model with a cubic characteristic equation were discussed in this paper. There were obtained matching sufficient conditions for aperiodic transient PID tuning based on the known condition of none complex conjugate transfer function poles and approximate formulas for finding the exception in such process granting the complex-conjugate poles element. The aperiodic transition has been provided by using the PID regulator in the context of none of loops elements with the resonant behavior with the best time response.The achievement of * Address correspondence to this author at the National Research Nuclear University “MEPhI”, 115409, Kashirskoe shosse, 31, Moscow, Russia; Tel: 8 (495) 687-23-41; E-mail: vmaslennikov@mail.ru Received: April 18, 2018 Revised: June 5, 2018 Accepted: July 20, 2018 roots of cubic equations.
