Huy N. Nguyen2, Mihir Pandya2 IBM Research, Rüschlikon, Switzerland, Freescale Semiconductor, Austin, TX 1 2 MicroServers integrate an entire server motherboard into a single Server-on-aChip (SoC), excluding DRAM, NOR-boot and power conversion circuits. This technology has evolved to 64b processing able to run server-class operating systems (OS), and the newest SoCs also target cloud computing and business SW [1]. The DOME μServer [2] packages the T4240 SoC in a dense node. Figure 4.4.7(a) shows the 239mm2 T4240 die with ~1.7B transistors including 111M bits of SRAM and 6M flipflops, implemented in 28nm bulk technology with 10 levels of copper interconnect. It has 3 clusters each with 4 e6500 cores. This core is 64b Power ArchitectureTM compliant and is fully dual-threaded with simultaneous multi-threading. It operates up to 1.8GHz and achieves 8.7CoreMark/MHz in dual-thread mode. Each core shares one floating-point and
