the Design of Display Processors</i>, Comm. ACM, Vol. 11, no. 6,

June 1968)] Term used to refer to a well-known effect whereby function in a
|
||
computing system family is migrated out to special-purpose peripheral
|
||
hardware for speed, then the peripheral evolves toward more computing power
|
||
as it does its job, then somebody notices that it is inefficient to support
|
||
two asymmetrical processors in the architecture and folds the function back
|
||
into the main CPU, at which point the cycle begins again.</p><p>Several iterations of this cycle have been observed in
|
||
graphics-processor design, and at least one or two in communications and
|
||
floating-point processors. Also known as <span class="firstterm">the
|
||
Wheel of Life</span>, <span class="firstterm">the Wheel of
|
||
Samsara</span>, and other variations of the basic Hindu/Buddhist
|

theological idea.
