MIMOLA is a language for the optimized design of digital processors, based upon computing resource utilizations for typical programs. It has been used for the design of a well-structured, fast, parallel and microprogrammable processor. Although not larger than a conventional minicomputer, it is about 26 times faster. It proves, that microcode need not be larger than equivalent machinecode. This paper also discusses possible architecture alternatives with low cost/performance ratios. O
