Chapter 1. Origins of Mac OS X
1 Chapter 1. Origins of Mac OS X "Most ideas come from previous ideas." Alan Curtis Kay The Mac OS X operating system represents a rather successful coming together of paradigms, ideologies, and technologies that have often resisted each other in the past. A good example is the cordial relationship that exists between the command-line and graphical interfaces in Mac OS X. The system is a result of the trials and tribulations of Apple and NeXT, as well as their user and developer communities. Mac OS X exemplifies how a capable system can result from the direct or indirect efforts of corporations, academic and research communities, the Open Source and Free Software movements, and, of course, individuals. Apple has been around since 1976, and many accounts of its history have been told. If the story of Apple as a company is fascinating, so is the technical history of Apple's operating systems. In this chapter,[1] we will trace the history of Mac OS X, discussing several technologies whose confluence eventually led to the modern-day Apple operating system. [1] This book's accompanying web site (www.osxbook.com) provides a more detailed technical history of all of Apple's operating systems. 1 2 2 1 1.1. Apple's Quest for the[2] Operating System [2] Whereas the word "the" is used here to designate prominence and desirability, it is an interesting coincidence that "THE" was the name of a multiprogramming system described by Edsger W. Dijkstra in a 1968 paper. It was March 1988. The Macintosh had been around for four years. -

Signature of Author . Cape Town South Africa May 12, 2013 University of Cape Town i Abstract This dissertation describes the design and implementation of a mechanism that automates gateware1 device detection for reconfigurable hardware. The research facilitates the pro- cess of identifying and operating on gateware images by extending the existing infrastruc- ture of probing devices in traditional software by using the chosen technology. An automated gateware detection mechanism was devised in an effort to build a software system with the goal to improve performance and reduce software development time spent on operating gateware pieces by reusing existing device drivers in the framework of the chosen technology. This dissertation first investigates the system design to see how each of the user specifica- tions set for the KAT (Karoo Array Telescope) project in [28] could be achieved in terms of design decisions, toolchain selection and software modifications. -

Power Architecture® ISA 2.06 Stride N Prefetch Engines to Boost Application's Performance
Power Architecture® ISA 2.06 Stride N prefetch Engines to boost Application's performance History of IBM POWER architecture: POWER stands for Performance Optimization with Enhanced RISC. Power architecture is synonymous with performance. Introduced by IBM in 1991, POWER1 was a superscalar design that implemented register renaming andout-of-order execution. In Power2, additional FP unit and caches were added to boost performance. In 1996 IBM released successor of the POWER2 called P2SC (POWER2 Super chip), which is a single chip implementation of POWER2. P2SC is used to power the 30-node IBM Deep Blue supercomputer that beat world Chess Champion Garry Kasparov at chess in 1997. Power3, first 64 bit SMP, featured a data prefetch engine, non-blocking interleaved data cache, dual floating point execution units, and many other goodies. Power3 also unified the PowerPC and POWER Instruction set and was used in IBM's RS/6000 servers. The POWER3-II reimplemented POWER3 using copper interconnects, delivering double the performance at about the same price. Power4 was the first Gigahertz dual core processor launched in 2001 which was awarded the MicroProcessor Technology Award in recognition of its innovations and technology exploitation. Power5 came in with symmetric multi threading (SMT) feature to further increase application's performance. In 2004, IBM with 15 other companies founded Power.org. Power.org released the Power ISA v2.03 in September 2006, Power ISA v.2.04 in June 2007 and Power ISA v.2.05 with many advanced features such as VMX, virtualization, variable length encoding, hyper visor functionality, logical partitioning, virtual page handling, Decimal Floating point and so on which further boosted the architecture leadership in the market place and POWER5+, Cell, POWER6, PA6T, Titan are various compliant cores.
