Dear Students! Graded-MDB will be launched on July 10, 2012 and it will remain open for two days.

GDB Topic:
“Do you agree with the statement that Multi-core processor is a special kind of a multiprocessor? If yes or no state your reasons to support your answer.”

A concise, coherent and to the point comment is preferred over lengthy comment having irrelevant details. Your comment must not be more than 6-8 lines. Comments, posted on regular Lesson's MDB or sent through email will NOT be considered in any case. Any request about such an acceptance will not be catered.

Best of Luck!

tell me what u say

totly wrong bhai g 

u are wrong

which is right mohsan bro?

this right 100%

yes why not  ,so we can say that a multi-core processor is an integrated circuit (IC) to which two or more processors have been attached for enhanced performance, reduced power consumption, and more efficient simultaneous processing of multiple tasks . A dual core set-up is somewhat comparable to having multiple, separate processors installed in the same computer, but because the two processors are actually plugged into the same socket, the connection between them is faster. Ideally, a dual core processor is nearly twice as powerful as a single core processor. In practice, performance gains are said to be about fifty percent: a dual core processor is likely to be about one-and-a-half times as powerful as a single core processor


it is also right 99%

CPU, or Central Processing Unit, is what is typically referred to as a processor. A processor contains many discrete parts within it, such as one or more memory caches for instructions and data, instruction decoders, and various types of execution units for performing arithmetic or logical operations.

A multiprocessor system contains more than one such CPU, allowing them to work in parallel. This is called SMP, or Simultaneous Multiprocessing.

A multi*core* CPU has multiple execution cores one one CPU. Now, this can mean different things depending on the exact architecture, but it basically means that a certain subset of the CPU's components is duplicated, so that multiple "cores" can work in parallel on separate operations. This is called CMP, Chip-level Multiprocessing.

If I understand correctly, multi core processing involves more then one core existing on a single cpu socket. Multiprocessing involves multiple sockets housing cpu's. So a multiprocessor would be a device that has multiple sockets for multiple cpu's or a single socket with a multicore processor. So multicore socket is doing what multiprocessing does, process code with multiple processors that can act independently of each other. The difference being a mulcore system is more compact, though it has less capabilites
