1.2. Terminology for Intel Agilex® 7 M-Series FPGAs
Network-on-Chip based communications structure between elements only in Intel Agilex® 7 M-Series FPGAs.
|Hard Memory NoC
|The NoC subsystem implemented as a hard block in the Intel Agilex® 7 M-Series FPGA for interfacing with high-bandwidth memory and external memory interfaces.
|Horizontal NoC (HNoC)
The Intel Agilex® 7 M-Series FPGA implements the NoC as two independent hard memory NoCs running horizontally along the top edge and bottom edge of the die.
|NoC Initiator (INIU)
The bridge between the AXI4 manager in user logic and the hard memory NoC.
|NoC Target (TNIU)
The bridge between the AXI4 subordinate IP in the periphery and the hard memory NoC.
An optional implementation of the NoC initiator where the read response data is written directly to M20K memory blocks.
The in-package, high-bandwidth memory available in Intel Agilex® 7 M-Series FPGAs.
|Pseudo BL8 Transaction
|For HBM2E, you can enable data access granularity of 64B (64 bits per Pseudo-Channel at BL8) which can achieve greater efficiency. By default, data access granularity is 32B (64 bits per Pseudo-Channel at BL4).
Function that initiates transactions on an AXI4 interconnect.
Function that responds to transactions on an AXI4 interconnect.
General purpose I/O bank available in Intel Agilex® 7 M-Series FPGAs.
|Bypasses the NoC. This mode applies only to EMIF configuration, with EMIF in bypass mode.
|EMIF in bypass mode
|Any instance of the External Memory Interfaces (EMIF) IP that you configure with PHY_NOC_EN=false. When PHY_NOC_EN=false, the access mode is through the fabric, in either sync or async mode).
|Dedicated phase lock loop (PLL) for the hard memory NoC.
|Byte lane (BL)
|Synonymous with an IO12, or I/O lane.
|Subsystem manager for the hard memory NoC.
|Secure Device Manager (SDM)
|There is no connection between the SDM and the hard memory NoC, and all signals from the SDM bypass the hard memory NoC.
|Universal interface block that is a silicon bridge to connect FPGA I/O to the HBM2E memory device.
|one dimm, one rank
|one dimm, two ranks
