q which things should microprocessor validatea microprocessor should validate powerful addressing modes more addressing capability more throughput
q show the major benefits of microprocessormicroprocessor is a complete cpu on a single chip the major benefits of microprocessor are powerful
q fundamental differences between risc and cisc architecturefundamental differences between risc and cisc architecture the following table lists
q explain about risc pipelininginstruction pipelining is frequently used to increase performance lets consider this in context of risc architecture
q diffrence between risc and cisc architectureciscs provide better support for high-level languages since they include high-level language constructs
characteristics of large-register-file and cache organizationslarge register filecachehold local variables for almost all functions this saves
generally the register storage is faster than cache andmain memory also register addressing uses much shorter addresses than addresses for cache and
q vlsi implementation of control unita main potential advantage of risc is vlsi implementation of microprocessor vlsi technology has decreased the
q explain high performance of instruction executionhigh performance of instruction execution while mapping of hll to machine instruction the compiler
q risc performance using optimizing compilersperformance using optimizing compilers as instructions are simple compilers can be developed for
simple instruction formatsrisc uses simple instruction formats usually only one or a few instruction formats are used in these machines instruction
q explain addressing modes in riscsimple addressing modes another benefit is the use of simple addressing modes risc machines employ simple register
q register-to-register operands in riscregister-to-register operands in risc machines operation which access memories are load and store all other
q instruction per cycle in riscone instruction per cycle a machine cycle is total time taken to fetch two operands from registers perform alu
q explain about risc architecturelets first list some significant considerations of risc architecture1 risc functions are kept simple unless there is
q origin of riscin the 1980s a new philosophy developed having optimizing compilers which could be used to compile normal programming languages down
q observations of high level language programobservations integer constants appeared nearly as frequently as structures or arrays most of the scalars
with the increasing use of more and higher level languages manufacturers had offered more powerful instructions to support them it was claimed that a
q code density and smaller faster programsmemory was very expensive in older computer so there was a need of less memory utilization which is it was
q explain microcode and vlsi technologyit is considered that cu of a computer be assembled using two ways create micro-program which execute
in the past there was a large gap between speed of a memory andprocessor so a subroutine execution for an instruction for illustration floating point
q show various risc processorsrisc has fewer design bugs and its simple instructions decrease design time sodue to all the above important reasons
q show the importance of risc processorsreduced instruction set computers recognize a comparatively limited number of instructions one benefit of a
the goal of computer architects is to design computers that are cheaper and more powerful than their predecessors a cheaper computer has low hardware
q decoding of slightly encoded micro-instructionsgenerally micro-programmed control unit designs are neither totally unencoded nor highly encoded
