Bit slice processor with examples
We will learn about an important concepts related to computer architecture - Bit slice processor.
What is bit slice processor?
A bit slice processor in computer architecture is constructed from processor modules of smaller bit width.
Each of these processes one bit field of an operand. Each processor module chip typically includes ALU and few registers. Using smaller size processors, we can design processor of any word length.
a 4-bit bit slice processor includes a register file and an ALU to perform operations on 4-bit data, so that four such chips can be combined to build a 16-bit processor unit.
The chip count which results in high power dissipation and poor reliability is the major concern of MSI functional blocks. To eliminate this scenario (problem), a new technique called bit slice processor is used due to advancement in fields of IC technology.
Examples of bit slice processor
Given below are few examples of bit slice processors:
Intel's 3000-family, and
AMD's AM2900 family.
