Detailed Description

template<UI num_ip = NUM_IC>
struct VCAllocator< num_ip >

Module to represent a Virtual channel allocator.

This module defines a Virtual channel allocator (VCA) in a network tile

Member Function Documentation

template<UI num_ip> void VCAllocator< num_ip >::allocate_VC (   )

process sensitive to VC request Process sensitive to incoming request for virtual channel allocation reads request allocates virtual channel in the requested channel on neighbor tile returns allocated vcid and ready signal

template<UI num_ip> sc_uint< VCS_BITSIZE+1 > VCAllocator< num_ip >::getNextVCID (  int  dir, int  dir_from )

allocates vcid in the requested channel Method that implements virtual channel allocation Parameters: o/p direction (neighbor tile) in which virtual channel is requested i/p direction (IC) from which request is recieved return allocated VC id

template<UI num_ip = NUM_IC> VCAllocator< num_ip >::SC_CTOR (  VCAllocator< num_ip >   )

Constructor.

template<UI num_ip> void VCAllocator< num_ip >::setTileID (  UI  id, UI  port_N, UI  port_S, UI  port_E, UI  port_W )

sets tile ID and id corresponding to port directions Method to assign tile IDs and port IDs

template<UI num_ip> void VCAllocator< num_ip >::update_credit (   )

process sensitive to credit input, updates credit (buffer status)
