o
Modern computers use a stored-program model for program
execution

o
Software does not exist without hardware!!

o
flexibility
o
For implementing a new application, same hardware can
be used with a different set of instructions
o
Converting software written in a high-level language to
machine language (compilation) is also a fast process
Software
10
o
How fast a software-based system executes depend upon
several factors
o
Roughly it can be mapped to the number of instructions,
number of clock cycles per instruction and the clock
frequency at which the processor runs
execution Time = #instructions x clock cycle/instruction x clock period
o
Practically we cannot keep on increasing clock frequency
or reduce clock cycle/instruction

o
In stored program model, often data/instruction needs to be
fetched from external memory
o
Inter-chip communication is one of the most power
consuming operation (due to large driving current)
o
Again since applications need to be mapped to a fixed
hardware architecture, implementation may be suboptimal
increasing execution time and power consumption
Hardware
12
o
Hardware (here we are dealing only with digital circuits)
and built using gates and flip-flops
o
The major advantage of hardware is it can be custom
designed for a specific application

Their design and development process is more complex
and takes more time compared to software counterpart

o
In a hardware-software co-design approach we try to
exploit advantages of both domains
o
As a thumb rule, hardware is very efficient in implementing
data intensive applications
(usually referred as data path)
o
Software is more appropriate for
control intensive
applications
(usually referred as control path)
o
In a codesign approach, we implement data processing
portion of the system on custom hardware and use
software to control them

Software o Software is composed of code and data o Code corresponds to set of instructions supported by a processor o Data corresponds to registers and memory locations used by the code during execution 6
Software o Aim Add 20H and 30H and store the result in memory C Code Assembly Code Hex Code char a=20; MOV A,#20 3E 20 char b=30; MOV B,#30 06 30 char c; c = a+b; ADD A,B 80 MOV [000A],A 32 0A 00 7
Software o Modern computers use a stored-program model for program execution 8
Software o Software does not exist without hardware!! o In software-based systems, applications are implemented as different set of instructions (software) mapped to the same hardware architecture o This is the greatest advantage of software also flexibility o For implementing a new application, same hardware can be used with a different set of instructions o Converting software written in a high-level language to machine language (compilation) is also a fast process 9
Software o How fast a software-based system executes depend upon several factors o Roughly it can be mapped to the number of instructions, number of clock cycles per instruction and the clock frequency at which the processor runs execution Time = #instructions x clock cycle/instruction x clock period o Practically we cannot keep on increasing clock frequency or reduce clock cycle/instruction 10
Software o Another limiting factor of software implementation is power consumption o In stored program model, often data/instruction needs to be fetched from external memory o Inter-chip communication is one of the most power consuming operation (due to large driving current) o Again since applications need to be mapped to a fixed hardware architecture, implementation may be suboptimal increasing execution time and power consumption 11
Hardware o Hardware (here we are dealing only with digital circuits) and built using gates and flip-flops o The major advantage of hardware is it can be custom designed for a specific application o This increases their performance (throughput) and power consumption compared to a software implementation o But hardware is inherently inflexible o Their design and development process is more complex and takes more time compared to software counterpart 12
Hardware-Software o In a hardware-software co-design approach we try to exploit advantages of both domains o As a thumb rule, hardware is very efficient in implementing data intensive applications (usually referred as data path) o Software is more appropriate for control intensive applications (usually referred as control path) o In a codesign approach, we implement data processing portion of the system on custom hardware and use software to control them 13
