IBM vs. System/360 Computer Architectures
The first aspect of the research that should be pointed out is the important aspect of open-ended design. In this implementation the user of the machine will be able to change and modify the current functions and programs of the machine in a more feasible and generally applied manner. In other words, given the synchronicity in programming techniques and architecture of an open-ended machine, the engineering and manipulation of the applications and software or hardware run or implemented or upgraded on the machine will be applied more quickly and efficiently as a result of being open-ended and more manageable. The author proposes here that this aspect is most important for standardization and lucidity in implementation. Of course, it goes without saying that the general motivation for computer design and architecture has concomitance in feasibility and "user-friendly" generalities. When the author introduces the idea of general-purpose functionality, he attempts to realize a sort of logical provenience in dictation of style in architecture of the System/360. This, of course, is well defined in stating again that the smaller components that make up the greater system should be defined and acquired first. By doing this, the sy
Programs dependent on one machine in the series should run according to trend and speed increase as per the definitions provided by IBM for each concomitant machine in the series of the System/360. In arithmetic, sign representations, variable- versus fixed length decimal fields, decimal accumulators versus storage-storage operation, field specification, and ASCII versus BCD codes, the most apparent trend the author included in each choice was efficiency in baser components. By evolution, in many aspects, it is a development of systems created and defined in the past and redesigned to better fit the commerciality of current systems. The gates and fundamental hardware components limit these decisions significantly but they outline where the architecture intrinsically handles bits and byte representations. The decisions made in data format are rather basic. Commercialism in computing in the past brought BCD to the forefront, while ASCII is an international standard in character representation. In the final analyses of storage and hierarchical structuring for storage components, the decision is made to use the flexible addressed-register organization. Byte-byte transfer is best represented with the variable formatted decimal fields, and the effective usage of both ASCII and BCD code interchanges are a result of previous hardware (specifically CPU) dependent past decisions. This is true good base design, as the structure of the architecture in the series has given space to implement slightly higher level tools, and as described in the report it will follow that space and storage hierarchies can grow more effectively and be more efficient in design. For example, the choice of two's complement is easier to implement as the hardware components provide a simpler and cheaper solution. The application of character size, word format, word size, instruction field, number of index registers, input-output implementation, instruction set layout, storage capacity, character code, etc. Such things as outlined are code-independence, individual bit manipulation, general addressing, and I/O control. Efficiency in this case is best achieved, as outlined in the report, as speed in the base 16 application. stem has a solid base from which to begin defining the more intrinsic values accumulated by higher-level machine design. Such system implementations as decimal-base computational significance to binary, or others include mixed-radix.
