CS-01 Computer Fundamentals
Hints For Revision - Block IV
Parallel
processing - Emerging computer technology that
allows more than one computation at the same time.
Classification
of parallel computers
- Single Instruction Single Data (SISD)
- Single Instruction Multiple Data (SIMD)
- Multiple Instruction Single Data (MISD)
- Multiple Instruction Multiple Data (MIMD)
Types
of parallel processors
- Array processors
- Distributed Architecture
- Multiprocessors
- Data flow architectures
Interconnection
structures
- Time - shared common bus
- Multiport memory
- Crossbar switch
Cache - A section of very high-speed memory that is used to temporarily store
data before it is used by the PC’s processor. A cache can dramatically
speed up the effective rate at which data is read from a hard disk drive.
Cache
Coherence - It is a situation in which all the
Cache copies of shared variables in a multiprocessor system do not have
the same value at all the times.
Pipelining
and Vector Processing
Memory
