Computer Engineering by S. A. Lebedev (Ed.)

This publication is concerned with a series of questions in computer engineering: the power supply system of the high-speed electronic computer of the Academy of Sciences of the U.S.S.R.; new elements and units for computers; a method of control of the arithmetic unit; a method of selecting the required word from the dictionary in machine translation; and present-day computer terminology. The publication was drawn up by specialists in the design and working of electronic computers. Besides papers from the Institute of Precision Mechanics and Computer Engineering, this publication contains articles by authors from other organizations concerned with computer engineering.

Translated From the Russian by JANE STUART
Translation edited by J.P. CLEAVE and E.A. SOWAN

Wanted #ComputerArchitecture pedantry.

What distinction do you guys make between a "cache block" and a "cache line" ?

Ah, the ancient art of computer architecture comparison, reduced to a and cookie-enabled abyss 🤦‍♂️💻. Because who doesn't love waiting for a website to tell us the earth-shattering differences between two processor types that about five people care about? 🍪🔄

‘A Seymour Cray Perspective’
Gordon Bell’s closing quote from Jim Gray
November 10, 1997

#seymourcray #computerarchitecture #quotes

1997 lecture slide by Gordon Bell, quoting Jim Gray on Seymour Cray: Seymour built simple machines - he knew that if each step was simple it would be fast.

When asked what kind of CAD tools he used for the CRAY1 he said that he liked #3 pencils with quadrille pads. He recommended using the back sides of the pages so that the lines were not so dominant.

When he was told that Apple had just bought a Cray to help design the next Mac, Seymour commented that he had just bought a Mac to design the next Cray.

This toot fosstodon.org/@interlisp/11512 led me via a reference to Edmund C. Berkeley (as coauthor with L. Peter Deutsch of "The LISP Implementation for the PDP-1 Computer", March 1964 and author of "Giant Brains, or Machines that Think", 1949) to the 1950 2-bit relay computer Simon and then to Harry Porter's Relay Computer:

By eighteen minutes in, if you can follow along, you'll understand how ALU function codes are selected.

I've never seen such a succinct explanation of a computer.

[Edit: the 3-bit ALU function codes are later wrapped in 8-bit opcodes, which trigger loads and selects from the data and address buses. This is exposition at its finest!]

A still from the linked video. A simplified diagram of an ALU (arithmetic and logic unit) which implements seven instructions (and a NOOP): ADD, INC (increment), AND, OR, XOR, NOT and SHL (shift left). The trick is in the 3-to-8 decoder, which takes as input a three-bit number representing an opcode, and whose output on one of eight lines enables the circuit for a given operation to act on two eight-bit numbers coming into the ALU.
