Explanation:

Vector and Array Machines
- Vector and array machines belong to the Single Instruction/Multiple Data (SIMD) category in Flynn's classification of computers.
- These machines are designed to perform the same operation on multiple data elements simultaneously.
- In vector machines, a single instruction operates on a vector of data elements in parallel.
- Array machines extend this concept by operating on multi-dimensional data arrays in parallel.

Single Instruction/Multiple Data Category
- In the SIMD category, a single instruction is executed on multiple data elements at the same time.
- This architecture improves performance for tasks that involve processing large amounts of data in parallel.
- Vector and array machines are well-suited for scientific computing, image processing, and other applications that benefit from parallelism.

Conclusion
- Therefore, vector and array machines are classified under the Single Instruction/Multiple Data category in Flynn's taxonomy of computers.

Similar Computer Science Engineering (CSE) Doubts

An instruction pipeline has five stages where each stage take 2 nanoseconds and all instruction use all five stages. Branch instructions are not overlapped. i.e., the instruction after the branch is not fetched till the branch instruction is completed. Under ideal conditions,a. Calculate the average instruction execution time assuming that 20% of all instructions executed are branch instruction. Ignore the fact that some branch instructions may be conditional.b. If a branch instruction is a conditional branch instruction, the branch need not be taken. If the branch is not taken, the following instructions can be overlapped. When 80% of all branch instructions are conditional branch instructions, and 50% of the conditional branch instructions are such that the branch is taken, calculate the average instruction execution time. Correct answer is 'Each stage is 2 ns.'. Can you explain this answer?

An instruction pipeline has five stages, namely, instruction fetch (IF), instruction decode and register fetch (ID/RF), instruction execution (EX), memory access (MEM), and register writeback (WB) with stage latencies 1 ns, 2.2 ns, 2 ns, 1 ns, and 0.75 ns, respectively (ns stands for nanoseconds). To gain in terms of frequency, the designers have decided to split theID/RF stage into three stages (ID, RF1, RF2) each of latency 2.2/3 ns. Also, the EX stage is split into two stages (EX1, EX2) each of latency 1 ns. The new design has a total of eight pipeline stages. A program has 20% branch instructions which execute in the EX stage and produce the next instruction pointer at the end of the EX stage in the old design and at the end of the EX2 stage in the new design. The IF stage stalls after fetching a branch instruction until the next instruction pointer is computed. All instructions other than the branch instruction have an average CPI of one in both the designs. The execution times of this program on the old and the new design are P and Q nanoseconds, respectively. The value of P/Q is __________. Correct answer is '1.54'. Can you explain this answer?
