A '''high-level language computer architecture''' ('''HLLCA''') is a [[computer architecture]] designed to be targeted by a specific [[high-level programming language]] (HLL), rather than the architecture being dictated by hardware considerations. It is accordingly also termed '''language-directed computer design,''' coined in {{harvtxt|McKeeman|1967}} and primarily used in the 1960s and 1970s. HLLCAs were popular in the 1960s and 1970s, but largely disappeared in the 1980s. This followed the dramatic failure of the [[Intel 432]] (1981) and the emergence of [[optimizing compiler]]s and [[reduced instruction set computer]] (RISC) architectures and RISC-like [[complex instruction set computer]] (CISC) architectures, and the later development of [[just-in-time compilation]] (JIT) for HLLs. A detailed survey and critique can be found in {{harvtxt|Ditzel|Patterson|1980}}.
