DATA-PATH

Core Request

RD/WR Request from Core. A Load/Store from a Cores thread is sent to the Fabric

The Data Path of Request from Core to Fabric.

• Q500) C2F_Req500H -> C2F_NextBufferQnnnH
• Q501) C2F_BufferQnnnH-> C2F_ReqQ501H -> RingoutputQ501H
• Q502) RingoutputQ502H

Memory Response

RD_RSP from Memory with Data.
A Read request that originated from Ring input to the Local memory - Read Response back to Fabric the Data

The Data Path of a Read Response from Local Memory to Fabric.

• Q500) F2C_Rsp500H -> F2C_NextBufferQnnnH
• Q501) F2C_BufferQnnnH-> F2C_RspQ501H -> RingoutputQ501H
• Q502) RingoutputQ502H

Ring Input

Ring Input has 3 Data Paths option:

1. Pass through (no Alocation in Buffers)

• Q500) RingInputQ500H
• Q501) RingInputQ501H -> RingoutputQ501H
• Q502) RingoutputQ502H

2. RD/WR Req to Local Memory (Alocting F2C Buffer entry)

• Q500) RingInputQ500H
• Q501) RingInputQ501H -> F2C_NextBufferQnnnH
• Q502) F2C_BufferQnnnH -> F2C_ReqQ502H

3. RD_RSP Response to a Core Request (Alocting C2F Buffer entry)

• Q500) RingInputQ500H
• Q501) RingInputQ501H -> C2F_NextBufferQnnnH
• Q502) C2F_BufferQnnnH -> C2F_RspQ502H
