WebJun 22, 2024 · Extracting similar datapath bit slices which handle highly parallel bit operations can help a modern placer to obtain better solutions for datapath-oriented designs. A current state-of-the-art datapath bit slicing method achieves the best extraction results using a network-flow-based algorithm. However, this work has two major drawbacks: (1) … WebMar 6, 2024 · Bit slicing is a technique for constructing a processor from modules of processors of smaller bit width, for the purpose of increasing the word length; in theory to make an arbitrary n -bit central processing unit (CPU). Each of these component modules processes one bit field or "slice" of an operand.
WebBit Slicing and Bit Concatenation This section describes how to use the functions bitsliceget and bitconcat to access and manipulate bit slices (fields) in a fixed-point or integer word. As an example, consider the operation of swapping the upper and lower 4-bit nibbles of an 8-bit byte. Web3 Answers. Sorted by: 25.

WebBit slicing ¶ The intbv type also supports bit slicing, for both read access assignment. For example: >>> a = intbv(24) >>> bin(a) '11000' >>> a[4:1] intbv (4) >>> bin(a[4:1]) '100' >>> a[4:1] = 0b001 >>> bin(a) '10010' >>> a intbv (18) In accordance with the most common hardware convention, and unlike standard Python, slicing ranges are downward.
