Flow control for a multiple flow control unit interface

A chiplet system comprising:

• a first chiplet comprising a memory controller, and further including logic configured to perform operations comprising:
• receiving, from a source, on a transfer cycle, multiple flow control units (flits), two or more of the multiple flits being directed to a first virtual channel, a flit of the multiple flits being directed to a second virtual channel;
• copying the two or more flits to a first buffer associated with the first virtual channel;
• and
• copying the flit to a second buffer associated with the second virtual channel.

A non-transitory machine-readable medium that stores instructions that, when executed by a system, cause the system to perform operations comprising:

• receiving, from a source, on a transfer cycle, multiple flow control units (flits), two or more of the multiple flits being directed to a first virtual channel, a flit of the multiple flits being for a second virtual channel;
• copying the two or more flits to a first buffer associated with the first virtual channel;
• and
• copying the flit to a second buffer associated with the second virtual channel.

A method comprising:

• copying the two or more flits to a first buffer associated with the first virtual channel;
• and
• copying the flit to a second buffer associated with the second virtual channel.
