Abstract

Matching the instructions and their representations to the distributions of usage can save 75% of the space taken by contemporary machine representations. The gain in space may be accompanied by a reduction in execution time due to more efficient use of data paths. Variable-length codes can also eliminate all forms of overflow from machine-language, and greatly reduce the probability of overflow in data.
