/* This module contains slot construction and decomposition */

/* The six routines and 5 tables used in this module may be */
/* associated by functionality in the following manner: */

/* vselp[] <-> cl1[], cl2[] Conversions: */
/* */
/* Tables: cl1_vselp_table[] */
/* cl2_vselp_table[] */
/* */
/* Functions : get_cl1_cl2() */

/* */
/* Tables : NONE */
/* */
/* Functions: build_slot() */
/* get_slot_data() */
/* */
/* Functions: */
/* */
/* get_cl1_cl2() : This function extracts class bits (cl1[], cl2[]) */
/* from VSELP parameters (vselp[]) using the */
/* conversion tables: cl1_vselp_table[] and */
/* cl2_vselp_table[]. */
/* */
/* get_vselp() : This function extracts VSELP parameters */
/* (vselp[]) from class bits (cl1[], cl2[]) using */
/* the conversion tables: cl1_vselp_table[] and */
/* cl2_vselp_table[]. */
/* */
/* build_slot_data() : This function generates 260-bit slot data from */
/* the class 2 bits (cl2[]) and the cc0[] and cc1[] */
/* bitarrays using the conversion tables: */
/* cc0_table[], cc1_table[] and cl2_table[]. */
/* */
/* extract_slot_bits() : This function extracts the class 2 bits (cl2[]) */
/* and the cc0[] and cc1[] bit arrays from 260-bit */
/* slot data using the conversion tables: */
/* cc0_table[], cc1_table[] and cl2_table[]. */
/* */
/* build_slot() : This function formats a 324-bit slot from */
/* 260-bit slot data and the sync word for slot #1. */
/* */
/* get_slot_data() : This function extracts 260-bit slot data from a */
/* 324-bit slot. */
/* */
/* Tables: */
/* */
/* cl1_vselp_table[] : This table is used for vselp[] <-> cl1[] */
/* conversions. Each cl1[] bit has an associated */
/* two-element entry in this table. The 1st entry */
/* identifies the VSELP parameter associated with */
/* this bit, while the second entry identifies the */
/* specific bit in the VSELP parameter associated */
/* with this bit. */
/* */
/* cl2_vselp_table[] : This table is used for vselp[] <-> cl2[] */
/* conversions. Each cl2[] bit has an associated */
/* two-element entry in this table. The 1st entry */
/* identifies the VSELP parameter associated with */
/* this bit, while the second entry identifies the */
/* specific bit in the VSELP parameter associated */
/* with this bit. */
/* */
/* cc0_table[] : This table is used for slot_data[] <-> cc0[] */
/* conversions. Each cc0[] bit has a 1-element */
/* entry in this table which identifies the */
/* associated slot data bit index (0-259). */
/* */
/* cc1_table[] : This table is used for slot_data[] <-> cc1[] */
/* conversions. Each cc1[] bit has a 1-element */
/* entry in this table which identifies the */
/* associated slot data bit index (0-259). */
/* */
/* cl2_table[] : This table is used for slot_data[] <-> cl2[] */
