Convert a stream of unpacked bytes or shorts into a stream of packed bytes or shorts.
input: stream of int; output: stream of int.
This is the inverse of gr_packed_to_unpacked_XX.
The low bits_per_chunk
bits are extracted from each input byte or short. These bits are then packed densely into the output bytes or shorts, such that all 8 or 16 bits of the output bytes or shorts are filled with valid input bits. The right thing is done if bits_per_chunk is not a power of two.
The combination of gr_packed_to_unpacked_XX followed by gr_chunks_to_symbols_Xf or gr_chunks_to_symbols_Xc handles the general case of mapping from a stream of bytes or shorts into arbitrary float or complex symbols.

Confirm that ninputs and noutputs is an acceptable combination.
ninputs | number of input streams connected |
noutputs | number of output streams connected |
This function is called by the runtime system whenever the topology changes. Most classes do not need to override this. This check is in addition to the constraints specified by the input and output gr_io_signatures.
Reimplemented from gr_basic_block.
|
virtual |
Estimate input requirements given output request.
noutput_items | number of output items to produce |
ninput_items_required | number of input items required on each input stream |
Given a request to product noutput_items
, estimate the number of data items required on each input stream. The estimate doesn't have to be exact, but should be close.
Reimplemented from gr_block.
|
virtual |
compute output items from input items
noutput_items | number of output items to write on each output stream |
ninput_items | number of input items available on each input stream |
input_items | vector of pointers to the input items, one entry per input stream |
output_items | vector of pointers to the output items, one entry per output stream |
general_work must call consume or consume_each to indicate how many items were consumed on each input stream.
Reimplemented from gr_block.
