Решил почитать про историю создания ARM. Оказывается модель первого процессора была написана на Бейсике! http://www.ot1.com/arm/armchap1.html
Modelling the ARM1 instruction set
The first model of the ARM instruction set was written in BASIC, an approach which made it easy to set everything out and develop a prototype quickly, but proved less flexible when the hardware design needed to be tested and precise timings derived. The subsequent model of the ARM hardware was also written in BASIC. It required a BBC Micro fitted with a 6502 second processor to run, and no further testing was required to verify the design. A team of four people worked on the design, with the two VLSI designers working on the device sharing a single workstation. The actual physical design of the chips was achieved using VLSI Technology's custom design tools.
An event-driven simulator was designed, also in BASIC, which allowed the support chips, the video controller VIDC and memory controller MEMC (which both had slightly more complex timing requirements), and the I/O controller IOC, to be designed and tested. A development of this simulator, since rewritten in Modula-2 and then in C and known as ASIM, is still used by both Acorn and ARM Ltd. for design and testing today.
