bit slice

(architecture)
A technique for constructing a processor from modules, each of which processes one bit-field or "slice" of an operand. Bit slice processors usually consist of an ALU of 1, 2, 4 or 8 bits and control lines (including carry or overflow signals usually internal to the CPU). For example, two 4-bit ALUs could be arranged side by side, with control lines between them, to form an 8-bit ALU. A sequencer executes a program to provide data and control signals.

The AMD Am2901 is an example.

With further bit slice analysis, which takes more time, the 3-D system will show all three opens.
In comparison, 3-D systems excel at in-depth bit slice analysis, fully automated double-sided board inspection and z-height measurements.
