Seven Properties of Von-Neumann Architectures

    G Blaauw and F. Brooks on page 589 of their book Computer Architecture - Concepts and Evolution list seven "salient features" of von-Neumann architectures as proposed in the 1946 paper "Preliminary Discussion of the Logical Design of an Electonic Computing Instrument" by A. Burks, H. Goldstine, and J. von Neumann.

1. Single stream of instructions sequenced by instruction counter
2. Instructions stored with data in addressable memory
3. Instructions encoded as numbers - modifiable by arithmetic operations
4. Radix 2 (binary)
5. Word length long enough for scientific computation
6. Single Address - single operation instructions
7. Single Accumulator with MQ Register
