 *  Synopsis:
 *
 *      Miscellaneous resource related functions.
 *
 *  Interface Description:
 *
 *      Exported functions:
 *
 *          INT TI_RES_Cycle_Count(
 *              TOP     opcode
 *          )
 *
 *              How many consecutive cycles are affected by 'opcode's
 *              resources?
 *
 *          BOOL TI_RES_Can_Dual_Issue(
 *              TOP     opcode1
 *              TOP     opcode2
 *          )
 *
 *              Can the two specified instructions issue in the
 *              same cycle? (ignoring register constraints)
