Bit Slice
Returns the serial bit field from the input signal.
Description
The Bit Slice block returns a field of consecutive bits from the input signal. Specify the lower and upper bounds of the bit field using zero-base indexing in the LSB Position and MSB Position parameters. For the input word size , the values of LSB Position and MSB Position must meet the following constraints:
.
Ports
Input
Port_1 - input signal
scalar | vector | matrix
Input signal for which bit sectionalisation is performed. The input signal has a maximum bit width of 128.
Data types: Float16, Float32, Float64, Int8, Int16, Int32, Int64, Int128, UInt128, UInt8, UInt16, UInt32, UInt64, Bool, Fixed.
*Support for complex numbers: Yes
Output
Port_1 - output signal
scalar | vector | matrix
Output signal for which bit sectionalisation is performed. The word length of the output signal is calculated as
,
where and are the values of MSB Position and LSB Position parameters respectively.
