2. Fujitsu's Approach to Server System Development (1,011 KB)
In 1954, Fujitsu released FACOM100, the first relay computer to go on general release in Japan. Since then, it has been developing and providing new technology, under the theme of high performance and high reliability, to meet customer requirements amid the paradigm shift in ICT. Currently, the computer paradigm is changing owing to changes in corporate needs for ICT, technological innovation (e.g. virtualization technology), and changes in social environments such as global warming. There are needs for servers, which are part of ICT and Cloud computing infrastructure, to cope with these changes. This paper introduces Fujitsu's efforts for server strategies, server development and new server platforms against the background of the new computing paradigm and developments in Cloud computing. ---[Masaharu Yoshiyama, Koji Toriyama]

4. Clock Design Technology for High-Performance Processors (1.02 MB )
This paper introduces technology used in designing high-performance processors installed in servers so that they can distribute high-frequency clock signals among the whole chip. Clock synchronization systems must be designed so that clock signals can reach all synchronous sequential circuits in the processor at the same time. The influence of interconnect inductance cannot be ignored because clock frequencies have been getting higher, chip sizes have been getting larger, and low-resistance interconnects have appeared. Therefore, it is necessary to give sufficient consideration to inductance when designing such systems. The technology introduced in this paper uses both circuit design techniques to suppress clock skew and crosstalk noise, and CAD techniques which employ these techniques in an actual chip. The influence of inductance in clock transmission can be analyzed electrically by simulating actually designed clock circuits at the design stage, and this can help lead to higher performance processors. ---[Kinya Ishizaka, Hiroaki Komatsu]
5. High-Speed Interconnect Technology for Servers (1.66 MB )
We are developing high-speed interconnect technology for servers to meet customers' needs for transmitting huge amounts of data as quickly as possible. High-speed interconnect technology consists of high-speed I/O circuits and high-speed printed circuit boards (PCBs), and these technologies are optimized to achieve the target performance. This paper describes the architecture of I/O circuits that are part of efforts to develop high-speed transmission circuits. It also introduces the results of testing a prototype chip that was built to evaluate 20 Gb/s transmission. It goes on to describe efforts for improving PCB's simulation accuracy so that high-speed signals can be sent stably. For accurate simulations, we think it is important to accurately evaluate each part that makes up the transmission line and reflect the results in a simulation model. ---[Hiroyuki Adachi, Jun Yamada, Yasushi Mizutani]
6. Embedded SRAM Technology for High-End Processors (846 KB)
Fujitsu is the only company in Japan that develops its own processors for use in server products that support the social infrastructure. Its processor development strategy is to collaborate with the internal semiconductor group and simultaneously develop processor and semiconductor technology. This paper introduces SRAM development technology, which is a complex technology combining both semiconductor manufacturing and circuit systems. It fully meets conflicting server processor requirements such as high performance, small area and low power consumption. It is a technology that is essential for starting up new technology and having it fully operational at the same time. Primary cache SRAM speed determines the processor clock rate, while the access frequency of external memory, which is the data processing bottleneck, is determined by the RAM capacity of the high-density secondary cache SRAM. Thus SRAM is a key technology for server processors. As finer semiconductor technologies progress, various problems arise and the variability of the memory cells in SRAM gets bigger. Consequently, development of SRAM that meets the server processor requirements is getting critical. This paper describes our SRAM development methodology. ---[Hiroshi Nakadai, Gaku Ito, Toshiyuki Uetake]
