CPEN 4700 - Final Exam (Answered) 100% Harvard Architecture A type of computer system design in which the CPU uses separate memory interfaces for accessing instructions and data operands Index The portion of a memory address that determine where in cache (in what line) a given main memory address can be mapped MMU A hardware device that handles the details of address translation in a system with virtual memory Key Register In an associative memory, this determines the bit positions where matching is significant Ease of Use An architectural quality attribute that reflects how well a given instruction set architecture supports systems programming SAM This memory organization has variable access time and uses a relative address to locate the next item to be read or written Dirty Bit This is used to indicate that a cache line has been modified since it was loaded from main memory Benchmark A program(s) that are used to compare the performance of various computer systems Segment Fault This happens when a location within a variable-sized region of a program's logical memory is referenced, but it is not currently mapped to a location in physical main memory TLB A type of cache used to hold virtual-to-physical address translation information Transistor This technological development was an important factor in moving from "first-generation" to "second-generation" computers Valid Bit This is used to indicate that a cache line has been properly initialized from main memory This early computer used the stored program concept; its logical design was described in a 1945 report written by John von Neumann EDVAC A computer that used (or will use) an 8-bit microprocessor as its main CPU would most likely have a manufacture date of: 1981 A computer that use (or will use) ferrite core technology in its main memory system would most likely have a manufacture date of: 1965
