A multiprocessor organization for supporting relational data base management systems is presented. DIRECT has a MIMD (multiple instruction stream, multiple data stream) architecture. It can simultaneously support both intra-query and inter-query concurrency. The number of processors assigned to a query is dynamically determined by the priority of the query and the size of the relations it references. The size of a relation is not limited to that of the associative memory as in some previous data base machines. Concurrent updates are controlled through address translation tables which are maintained by a controlling processor. DIRECT is being implemented using LSI-11/03 microprocessors and CCD memories which are searched in an associative manner. A novel cross-point switch is used to connect the LSI-11 processors to the CCD memories. While cross-point switches have proven too expensive for use in general purpose parallel processors, their application in DIRECT demonstrates that these switches can be successfully used in specialized applications.

What are the key elements of a superscalar processor organization?
A superscalar processor organization is characterized by multiple execution units that allow for the simultaneous execution of multiple instructions in a single clock cycle. Key elements include instruction-level parallelism (ILP) capabilities, dynamic scheduling to optimize instruction execution order, and out-of-order execution to maximize resource utilization. Additionally, superscalar processors incorporate advanced techniques like branch prediction and speculative execution to further enhance performance by minimizing stalls and delays.
How is it possible for such a single processor system run multiple processes?

What are uni-processor and multi-processor?
seems you are a bit confused there,eh! it seems that u mean uni-core-processor and multi-core-processor. uni simply means 1 so its obvious it is a single core processor. (for eg. Pentium 4's) multi means multiple, so its obvious it is a multiple cores processor. (for eg. core2duo has 2 cores, core2quad has 4 cores, phenom ii x6 110t has 6 cores and so on)
If clock speed increases then what happens to processor speed?
Th clock speed is the processor speed. It is simply the amout of operations the processor can do per second. However if the processor has multiple cores, it will be as fast as number of cores * clock speed. Note that the processor speed is not the overall computer speed.

Splitting a single processor into multiple virtual machines is called what?

How many processor is required for multiprogramming?
Multiprogramming typically requires at least one processor to manage multiple processes concurrently. However, the effectiveness of multiprogramming can be enhanced with multiple processors, as this allows for true parallel execution of processes. In a single-processor system, the CPU rapidly switches between processes to provide the illusion of concurrent execution, while in a multi-processor system, multiple processes can run simultaneously. Ultimately, the number of processors needed depends on the specific requirements and workload of the applications being executed.
What is core i5 i4 i3 in computer?
A standard processor had one core like in P1, P2, P3, P4. It means it can performed only one task at a time. Now to make computer able to perform multiple tasks simultaneously it is being manufactured with multiple processors. A Dual-core processor has two cores. A Quad-core processor has four cores. An i3 processor has 2 cores. An i5 processor has 2 or 4 cores (depending on the model you have.) An i7 processor has 2, 4 or 6 cores (depending on the model you have.)
