>Patterson and colleagues first looked to build a modified RISC design to run the Smalltalk programming language (in a project known as SOAR, for Smalltalk On A RISC) and then to form the basis of a desktop workstation (known as SPUR, for Symbolic Processing Using RISC). "Symbolic Processing" here actually meant running Lisp: https://www2.eecs.berkeley.edu/Pubs/TechRpts/1986/6083.html https://www2.eecs.berkeley.edu/Pubs/TechRpts/1986/6083.html "The restricted processor count also allows us to build powerful RISC processors, which include support for Lisp and IEEE floating-point, at reasonable cost." "SPUR features include a large virtually-tagged cache, address translation without a translation buffer, LISP support with datatype tags but without microcode..."
