Quote: a computer hardware designer must use tolerances and statistical quality control [»dijkEW_1982]

Quote: a hardware designer must continually learn new technologies [»dijkEW_1982]

Quote: while hardware components have evolved rapidly, the target artifact is largely constant [»dijkEW_1982]

Quote: for software, the source components are largely stable, but the target artifacts keep changing [»dijkEW_1982]

Quote: software is especially complex because no two parts are alike while physical systems contain many repeated components [»brooFP_1986]

Quote: a prototype in engineering is a phase of the production process where a model is built for testing and guidance; not applicable to software [»floyC_1984]

Quote: hardware design and design checking of complex chips is heavily dependent on software [»wilkM10_1990]

Quote: a programmer can write and call a subroutine just as easily as invoking specially-built hardware; and without the maintenance cost [»utleAM6_1949]

Quote: use a hardware-walked, nested page table for VMMs; translates guest virtual addresses to host physical addresses; fast guest context switches and slightly slower TLB misses [»adamK10_2006]

Quote: analog systems can be reliable because they are continuous; small input changes cause small output changes [»parnDL12_1985]

Quote: computer hardware is reliable because its repetitive structure does not need exhaustive testing [»parnDL12_1985]

Quote: proving a hardware design is just another form of checking; does not catch specification errors and analog behavior [»wilkM10_1990]

Quote: hardware only brings down a single site; but software can bring down the system [»birrAD4_1982]

Quote: hardware timer interrupts are expensive; context switch, highest priority, poor cache locality [»aronM8_2000]

Quote: software VMM performs better than hardware VMM due to high VMM/guest transition costs and a rigid programming model; software VMM replaces traps with callouts [»adamK10_2006]
