This chapter begins with the author's recollections about Alan M. Turing while working at the National Physical Laboratory. It then discusses the Pilot ACE Instruction Set Architecture (ISA). The ISA is an important abstraction for the interface between the hardware and the low level software. It standardizes instructions, machine language bit patterns, among other things. It allows for the use of different implementations of the same architecture on different machines.
Keywords: Alan M. Turing, Pilot ACE, Instruction Set Architecture, computing
