To achieve the ambitious goals, the company ventured into development of full-custom LSI chips : a 4-bit slice arithmetic logic unit and 3-chip control unit.

It was widely used in the mainframe and other computers; it was implemented for the first time in EDSAC 2, which also used multiple identical " bit slices " to simplify design.

Combining components to produce bit slice products allowed engineers and students to create more powerful and complex computers at a more reasonable cost, using off-the-shelf components that could be custom-configured.

For one project, Gorman worked with AMD in the conceptualization of the Am2900 4-bit slice chip that was employed in Computer Automation's high-end processors and gained widespread acceptance in the marketplace.

Introduced in April 1982, the VAX-11 / 730, code-named " Nebula ", was a still-more-compact, still-lower-performance bit slice implementation of the VAX architecture.

The main advantage was that bit slicing made it economically possible in smaller processors to use matrix transformation, or as in the Xerox Alto, the combination of flexibility and speed, before discrete CPUs were able to deliver that.

The block cipher part is harder to bit slice, as the S-boxes involved are too large ( 8x8 ) to be efficiently implemented using logical operations, a prerequisite for bit slicing to be more efficient than a regular implementation.

In the 1970s and 1980s, a number of research and commercial computers used bit slicing, in which the CPU's arithmetic logic unit ( ALU ) was built from multiple 4-bit-wide sections, each section including a chip such as an Am2901 or 74181 chip.
