Reviving Bit-slice Technology in a Programmable Fashion
The term “Bit Slicing” was once dominant in history books as a technique for constructing a processor from processor modules of smaller bit width where each of these components processes one field or "slice" of an operand. Bit slice processors usually consist of an arithmetic logic unit (ALU) of 2, 4 or 8 bits and control lines. Using multiple, simpler ALUs was seen as a way to increase computing power in a cost-effective manner. The latest system-on-chip (SOC) technology revives bit-slice in a programmable fashion to serve the purpose of offloading the main CPU by intelligently assigning processing tasks to other processing.
