Single Instruction and Multiple Data stream (SIMD)
In this organisation, multiple processing elements are working under the control of a one control unit. It has multiple data stream and only one instruction. All the processing fundamentals of this organization get the same instruction broadcast from the CU. Main memory can also be separted into modules for producing multiple data streams acting as a distributed memory as shown in Figure 5. Thus, all the processing fundamentals simultaneously implement the same instruction and are supposed to be 'lock-stepped' together. Each processor obtain the data from its own memory and hence it has on distinct data streams. (Some systems also supply a shared global memory for communications.) Every processor must be allowed to finish its instruction previous to the next instruction is taken for implememtation. Thus, the implementation of instructions is synchronous. Examples of SIMD organisation are PEPE, ILLIAC-IV, , STARAN, BSP, DAP, MPP, and the Connection Machine (CM-1).
This type of computer organisation is represent as:
Convert hexadecimal BCH to decimal of form 0100 1000. Converting the hexadecimal BCH to decimal number firstly convert given number into two's compliment that is: 0100100
what is cascading rolback?
"Super ASCII", if it contains the character frequency equal to their ascii values. String will contain only lower case alphabets (''a''-''z'') and the ascii values will starts from
How many flip-flops are required to construct mod 30 counter ? Ans. Mod - 30 counter +/- requires 5 Flip-Flop as 30 5 . Mod - N counter counts overall ' N ' number of state
Think about call of two intrinsic functions discussed above for a 32-Processor (4×8) Multicomputer: The function call NUMBER_OF_PROCESORS () will return 32.
Q. Average data transfer rate in floppy? A floppy is about 0.64 mm thick and is available in diameters 5.25 inch and 3.5 inch. Data are arranged in form of tracks and sectors.
Quality of Service: This is assessed on the basis of customer's satisfaction.
Q. Collective Communications - Broadcast? Broadcast: Broadcasting can be done in two ways one of them is one to all and another one is all to all. In the matter of one to all b
The standards are for all testers using the IDE of Rational Robot to make their automated test scripts. The mission is to decrease maintenance costs when it comes to changes.
Example Calculation: If we see an example we are working with a set of examples like S = {s 1 ,s 2 ,s 3 ,s 4 } categorised with a binary categorisation of positives and negati
