Item Open Access Hardware accelerator design for data centers(IEEE, 2016-11) Yeşil, Şerif; Özdal, Muhammet Mustafa; Kim, T.; Ayupov, A.; Burns, S.; Öztürk, Özcan.As the size of available data is increasing, it is becoming inefficient to scale the computational power of traditional systems. To overcome this problem, customized application-specific accelerators are becoming integral parts of modern system on chip (SOC) architectures. In this paper, we summarize existing hardware accelerators for data centers and discuss the techniques to implement and embed them along with the existing SOCs. © 2015 IEEE.Item Open Access System-on-chip memory design for a domain-specific RISC-V processor(2023-05) Gülgeç, UtkuThe use of graph applications is common in many areas; however, irregular and data-driven memory access patterns combined with the large sizes of graph data results in performance loss in general-purpose computing systems. Existing studies proposed hardware accelerators often implemented on FPGAs to alleviate performance problems and improve energy efficiency while having less emphasis on programmability and flexibility. This thesis presents a hardware implementation of a domain-specific processor design for graph applications on a system-on-chip (SoC) platform accompanied by a design of a memory framework. The proposed system architecture improves the micro-architecture of a baseline design, integrates the baseline with an efficient system-on-chip bus communication protocol, and compares alternative memory framework implementations. The hardware is implemented on a state-of-the-art evaluation board. Popular graph benchmarks are used for performance evaluations of the implemented system, and various sensitivity analysis is done on newly added system parameters to determine the optimal system configuration. An analysis of power consumption and resource utilization is also provided. Overall, average speed-ups vary between 15% and 25% depending on the benchmark and graph data, while on-chip power consumption varies between 3.8 to 4.2 Watts depending on the system clock frequency.
