What is the role of 32 bit program counter (PC)
It holds the address of currently executing instruction
What is bit addressing
a number of bits can be directly accessed
Does Motorolla 68K processor have paged memory model
Yes

What is family of Sun SPARC
The Sun SPARC is a very popular processors belonging to the RISC (reduced instruction set computer) family of processors.
What is CISC
Complex instruction set computer
What is SPARC
Scalable Processor ARChitecture. SPARC is a 64 bit processor
What is ASI in SPARC
SPARC has a concept of ASI (Address Space Identifier); an 8 bit number that works similar to a segment.
There are how much global registers and how much alternate global registers in SPARC
8
What is the size of registers on SPARC
64 bit
What is register window in SPARC
One window is 24 registers and the active window is pointed to by a special register called Current Window Pointer (CWP).
