The AT&T Hobbit is a microprocessor design that AT&T Corporation developed in the early 1990s. It was based on the company's CRISP (C-language Reduced Instruction Set Processor) design, which in turn grew out of the C Machine design by Bell Labs of the late 1980s. All were optimized for running code compiled from the C programming language. The design concentrates on fast instruction decoding, indexed array access, and procedure calls. Its processor is partially RISC-like. The project ended in 1994 because the Hobbit failed to achieve commercially viable sales.
