This paper describes the design methodology employed in the design of the S/390@' Parallel Enterprise Server G4 microprocessors. Issues of verifying design metrics of area, power, noise, timing, testability, and functional correctness are discussed within the context of a transistor-level custom design approach. Practical issues of managing the complexity(More)
The IBM POWER6e microprocessor is a high-frequency (.5-GHz) microprocessor fabricated in the IBM 65-nm silicon-on-insulator (SOI) complementary metal-oxide semiconductor (CMOS) process technology. This paper describes the circuit, physical design, clocking, timing, power, and hardware characterization challenges faced in the pursuit of this industry-leading(More)
The IBM zEnterprise A 196 (z196) system, announced in the second quarter of 2010, is the latest generation of the IBM System z A mainframe. The system is designed with a new microprocessor and memory subsystems, which distinguishes it from its z10 A predecessor. The system has up to 40% improvement in performance for traditional z/OS A workloads and carries(More)
