Computer Organization and Design: The Hardware/Software by David A. Patterson, John L. Hennessy

By David A. Patterson, John L. Hennessy

The 5th version of machine association and Design-winner of a 2014 Textbook Excellence Award (Texty) from The textual content and educational Authors Association-moves ahead into the post-PC period with new examples, workouts, and fabric highlighting the emergence of cellular computing and the cloud. This generational swap is emphasised and explored with up-to-date content material that includes pill pcs, cloud infrastructure, and the ARM (mobile computing units) and x86 (cloud computing) architectures.

Because an figuring out of recent is key to reaching strong functionality and effort potency, this version provides a brand new concrete instance, "Going Faster," used in the course of the textual content to illustrate tremendous powerful optimization thoughts. additionally new to this version is dialogue of the "Eight nice Ideas" of machine architecture.

As with past variants, a MIPS processor is the center used to offer the basics of applied sciences, meeting language, computing device mathematics, pipelining, reminiscence hierarchies and I/O.

Sample text

At the time of writing, standard commodity microprocessors are designed to deliver at most two or four double-precision floating-point results per clock cycle. With typical clock frequencies between 2 and 3 GHz, this leads to a peak arithmetic performance between 4 and 12 GFlops/sec per core. As mentioned above, feeding arithmetic units with operands is a complicated task. The most important data paths from the programmer’s point of view are those to and from the caches and main memory. The performance, or bandwidth of those paths is quantified in GBytes/sec.

1 will describe how to predict performance for simple loops from basic parameters like cache or memory bandwidths and the data demands of the application. Storing data is a little more involved than reading. In presence of caches, if data to be written out already resides in cache, a write hit occurs. There are several possibilities for handling this case, but usually outermost caches work with a write-back strategy: The cache line is modified in cache and written to memory as a whole when 18 Introduction to High Performance Computing for Scientists and Engineers evicted.

Out-of-order execution and compiler optimization must work together in order to fully exploit superscalarity. However, even on the most advanced architectures it is extremely hard for compiler-generated code to achieve a throughput of more than 2–3 instructions per cycle. This is why applications with very high demands for performance sometimes still resort to the use of assembly language. 6), and was the fundamental design principle for the massively parallel Connection Machines in the 1980s and early 1990s [R36].
