High-level microprogramming with APL syntax
Richard F. Hobson, Patrick Hannon, Jonathan W. Thornburg · ACM SIGMICRO newsletter/SIGMICRO newsletter/SIGMICRO, TCMICRO newsletter · 1981
The article demonstrates how higher-level microprograms can be written in APL notation. With an architecture support package (ASP) defining and emulating target machine features, the resulting 'microAPL' code is directly APL executable. Firmware development is very straightforward. An implemented ASP, microAPL compiler, and microAPL linker are discussed. MicroAPL is also compared with S* notation.
