Hardwaresoftware tradeoffs in reliable software development. The user is generally not able to express his requirements in terms that the hardware specialist can deal with and, in any case, the link between the two is the marketing function. A realistic cryptanalysis of the a51 gsm stream cipher is presented as an illustration of such tradeoff. The communication path between the computer users and the computer manufacturer is not a very effective one, but it is the vehicle whereby hardware software tradeoffs are realized.

Part 1 of this twopart series looked at design considerations and tradeoffs using comparators as an example. Software is really the instructions that these devices execute, what causes them to take particular actions. Hardwaresoftware tradeoffs proceedings of the december 57. Another method is to provide automatic replication and coherence in software rather than hardware. The hardware is inexpensive and the graphics functions are implemented entirely in software. On hardwaresoftware tradeoffs in computer system design. The purpose of this paper is to discuss the concept of hardwaresoftware trade offs from the perspective of the hardware designer.
