BACKGROUND
A computer benchmark is a “program” that is used to determine relative computer core performance by evaluating benchmark execution time by that core. In the brainstorm on microcontrollers for automotive applications, an assembler functional benchmark for engine management, which is a typical example of embedded high-end microcontrol, was created. This report gives worked out routines of the functions if they were implemented in assembler language of the compared controllers: Motorola 68000, Intel 80C196, Philips 80C552 and Philips XA.
