Detailed Description

Converts a vector of bytes with 1 bit in the LSB to a byte with k relevant bits.

Example: k = 4 in = [0,1,0,1, 0x81,0x00,0x00,0x00] out = [0x05, 0x08]

k = 8 in = [1,1,1,1, 0,1,0,1, 0,0,0,0, 1,0,0,0] out = [0xf5, 0x08]

Constructor & Destructor Documentation

◆ pack_k_bits()

gr::blocks::kernel::pack_k_bits::pack_k_bits ( unsigned k )

Make a pack_k_bits object.

Parameters

k	number of bits to be packed.

◆ ~pack_k_bits()

gr::blocks::kernel::pack_k_bits::~pack_k_bits ( )

Member Function Documentation

◆ k()

int gr::blocks::kernel::pack_k_bits::k ( ) const

◆ pack()

void gr::blocks::kernel::pack_k_bits::pack	(	unsigned char *	bytes,
		const unsigned char *	bits,
		int	nbytes
	)		const

Perform the packing.

This block performs no bounds checking. It assumes that the input, in, has of length k*nbytes and that the output vector, out, has nbytes available for writing.

Parameters

bytes	output vector (k-bits per byte) of the unpacked data
bits	The input vector of bits to pack
nbytes	The number of output bytes

◆ pack_rev()

void gr::blocks::kernel::pack_k_bits::pack_rev	(	unsigned char *	bytes,
		const unsigned char *	bits,
		int	nbytes
	)		const

Same as pack() but reverses the bits.
