1. :: : : Look up Microsequencer and Microcode and Bit slicing . 2. Occasionally, physical limitations of integrated circuits made such practices as a bit slice approach necessary. 3. It was the first computer to have a microprogrammed control unit and a bit slice hardware architecture. 4. A bit slice component is a piece of an arithmetic logic unit ( ALU ), register file or microsequencer. 5. "' Bit slicing "'is a technique for constructing a word-length of a particular software design. 6. Custom CISCs were commonly constructed using " bit slice " computer logic such as the AMD 2900 chips, with custom microcode. 7. The DECADE chips implemented the data paths in 32-bit slices , and therefore the 21071 has two such chips while the 21072 has four. 8. The "'AL1 "'was an 8-bit bit slice which contained eight registers and an arithmetic logic unit ( ALU ). 9. The first few " little foonly " models were built from bit slice processors based on a design originally intended to be the F1's console computer. 10. When you see pancetta or prosciutto in the deli counter, it is as a huge block of it, with only a small bit sliced off from one end.
