    Excerpt: ... CS3615: Assignment 1 Due Date: 10.7.2004 Assignments will be accepted only at the beginning of the lecture 1) Search the Internet/library for information about the work of Zuse and how it differs from that of Von Neumann . Especially, clearly identify those Von Neumann principles absent in Zuse's work. 2) Give the binary representation of 34, 107, and 2012. What is the decimal value of: 10001111, 11111111, and 00011100? 3) Define the following terms in your own words: CPU, ALU, control unit, memory, instruction, address, interpretation, hierarchy, VonNeumann bottleneck, sequential processing, stored program concept. 4) In what respect is interpretation more general than translation? What benefits could a combination of both techniques bring? 5) Describe the interpretation elements (SYNT, SEM, .) of a handheld calculator. 6) Suppose you intend to analyze the performance of an interpretation. Identify the needed FUs and the type of tasks they work with. ...

    Excerpt: ... 1942 Finite Dimensional Vector Spaces (Click here to view our web site description.) Paul R. Halmos A s a newly minted Ph.D., Paul Halmos came to the Institute for Advanced Study in 1938 -even though he did not have a fellowship-to study among the many giants of mathematics who had recently joined the faculty. He eventually became John von Neumann 's research assistant, and it was one of von Neumann 's inspiring lectures that spurred Halmos to write Finite Dimensional Vector Spaces. The book brought him instant fame as an expositor of mathematics. Finite Dimensional Vector Spaces combines algebra and geometry to discuss the three-dimensional area where vectors can be plotted. The book broke ground as the first formal introduction to linear algebra, a branch of modern mathematics that studies vectors and vector spaces. The book continues to exert its influence sixty years after publication, as linear algebra is now widely used, not only in mathematics but also in the natural and social sciences, for studyi ...

    Excerpt: ... that supercomputers are very expensive. PC people like the structure (or the mess?) of PCs. Same thing for PC operating systems. Academics plead for new architecture principles but (wrongly?) without success: Dataflow machines Reduction machines Object-oriented machines 4 Goals of the Lectures Basic knowledge in computer architecture. Understanding the functionality of conventional computers (up to 99%) Understanding of the main evaluation criterion of computers, namely, performance. Programming of machines at the lowest level using assembly languages. Knowing the MIPS architecture and its assembly language. Basic knowledge for other fields: Operating systems Compilers Performance evaluation Systems programming Microprogramming And remember, you want to call yourself computer scientist, so you have to know about computers. 5 Von Neumann Architecture Principles (there are some!) of todays computer systems ...

    Excerpt: ... G22.3220-001 Cryptography and Imperfect Randomness January 24, 2006 Lecture 2 Lecturer: Yevgeniy Dodis Scribe: Carl Bosley and Jonghaw Lee Administrative notes: Everyone should sign up for the mailing list. Everyone who takes the class for credit is expected to do scribe notes, so be sure to sign up soon. Perfect randomness is often impractical and hard to obtain. So how do we make use of the imperfect randomness sources? This lecture we look at some examples of randomness extraction: Von Neumann s Coin, Markov Chains and Blums extraction. 1 Imperfect Randomness Randomness is used everywhere in Cryptography. Our examples last lecture assumed unbiased, independent random bits. This assumption is too strong for many real scenarios: Physical sources (hard disk latency, etc) are not truly independent and unbiased. Biometrics Partial key exposure Attacker learns part of the secret key, e.g. by microwaving a smartcard Question: Can we base cryptography on weaker (more realistic) assumptio ...

EE 367 Logic Design Lecture #29 Agenda 1. von Neumann Stored Program Computer Architecture Announcements (Monday, 4/14) n/a EE 367 Logic Design Spring 2008 Lecture #29 Page 1 von Neumann Computer von Neumann Stored Program Computer - "Stored Program" means the HW is designed to execute a set of pre-defined instructions - the program and data reside in a storage unit (i.e., memory) - to change the functionality of the computer, the program is changed (instead of the HW) - John von Neumann was a mathematician who described a computer architecture where the instructions and data reside in the same memory - this implies sequential execution - it is simple from the standpoint of state machine timing - the drawback is the " von Neumann bottleneck" in getting data into and out of memory in order for the computer to run - this architecture is what we are using in the labs on the Freescale microcontrollers EE 367 Logic Design Spring 2008 Lecture #29 Page 2 von Neumann Computer ...
