NOTE: There is no performance or frequency difference between the four DRAM controllers regardless whether they resides in the CL or the Shell logic. The CL will receive a SLVERR RRESP on an uncorrectable ECC error. Ryft CEO Des Wilson predicted at the time of the rollout that the “AWS marketplace will embrace heterogeneous computing principles with the advent of its new F1 instance, opening up a whole new set of data analytics capabilities.” guide on how to use the DRAM data retention mode to preserve the content of DRAM across AFI loads, There are multiple clocks and resets provided by the Shell to the CL. This interface is strictly used by the AWS FPGA Management Tools linux shell commands, and FPGA Management Library for integration with C/C++ applications, as well as AWS OpenCL Runtime ICD/HDL, and does not support any interface with the CL code. dw_cnt : 2 There are virtual LED/DIP switches that can be used to control/monitor CL logic. WARNING: If the stats interfaces are not connected, the DDR controllers will not function. The DMA_PCIS interface multiplexes the XDMA requests and PCIS requests. Crossing an SLR boundary is expensive from a timing perspective. An API is also provided through AWS Management Software. dw_cnt : 3 This can be used, for example, to push data from the CL to instance memory, or read from the instance memory. If you’d like to try FPGA-accelerated Postgres on an AWS EC2 F1 instance, just follow the steps below. There are three AXI-L master interfaces (Shell is master) that can be used for register access interfaces. It is advisable for the CL to implement enough buffering for 32 transactions per type so that it is aware of all issued transactions. a major block is spread out over multiple SLR's). sh_cl_ctl0[31:0] – Placeholder for generic Shell to CL control information. This BAR maps to the the OCL AXI-Lite interface. Transactions on AXI4 interface will be terminated and reported as SLVERR on the RRESP/BRESP signals and will not be passed to the instance in the following cases: PCIe BusMaster Enable (BME) is not set in the PCIe configuration space. Group A recipe must be defined in the AFI Manifest, which is included in the tar file passed to aws ec2 create-fpga-image AFI registration API. The Agility of F1: Accelerate Your Applications with Custom Compute Power. Custom Logic (CL) – Custom acceleration logic created by an FPGA Developer. AXI-Lite interfaces for register access, 4h. If the developer is using AWS OpenCL runtime Lib (as in SDAccel case), this interface will be used for performance monitors etc. The kit is avaliable on GitHub and includes all documentation on F1, internal FPGA interfaces, and compiler scripts for generating Amazon FPGA Images (AFIs). wstrb = 4’h1. These can be used to measure time inside of the CL. Each Die is called a “Super Logic Region” (SLR). The shell does not propagate the AXI-4 error responses to the PCIe bus. We made a simple example using Xilinx’s accelerators on AWS for image processing (edge detection and affine processing). The Shell supports DW aligned and unaligned transfers from PCIe (address is aligned/not aligned to DW-4byte boundary). Miscellanous Interfaces(vLED, vDIP..). is tagged with a revision number. This allows for optimized resource utilization of the FPGA (allowing higher utilization for the CL place and route region to maximize usable FPGA resources). This backpressure may be used to throttle XDMA requests if the XDMA requests may delay servicing PCIS requests such that the PCIS request responses would exceed the interface timeout time. Once the CL asserts a request on a particular bit[x], it should not assert a request for the same bit[x] until it has received the ack for bit[x] from the SH. Once your FPGA-accelerated application is ready, you can register it as an Amazon FPGA Image (AFI) and deploy it to F1 instances in just a few clicks. Transfers must adhere to all AXI-4 protocol rules. Hence the accelerated function on FPGA … Monetize your FPGA-accelerated Applications on AWS Marketplace. If the developer is using AWS OpenCL runtime lib(as in SDAccel case), this interface will be used for openCL Kernel access, cl_sh_apppf_irq_req[15:0] (from CL to SH), sh_cl_apppf_irq_ack[15:0] (from SH to CL), clock interaction report (see if paths between async clocks are erroneously being timed), physical implementation analysis (placement, routing). Each of the four DDR4 Controllers has an AXI-4 interface with a 512 bit data bus. The FPGA hardware is running at 250 MHz (clock recipe A1) and we transfer each video frame using one DMA request../canny fpga donaldson.avi edges_fpga.avi We use mplayer to verify the video matches the expected edge detection video edges_cpu.avi. With Amazon EC2 FPGA instances, each FPGA is divided into two partitions: Shell (SH) – AWS platform logic implementing the FPGA external peripherals, PCIe, DRAM, DMA, and Interrupts. The maximum frequency on clk_main_a0 is 250MHz. An AFI contains the FPGA bitstream that is ready to download to an FPGA. These can be used to control logic in the CL. c) PCIe BAR2 as a 64-bit prefetchable BAR sized as 64KiB.

However, for the DDR-4 controller that is instantiated in the Shell, DDRC, there is an AXI-4 interface between the Shell and CL.  Researchers can choose to share their completed Amazon FPGA Images (AFIs) with other groups or even sell them on the AWS marketplace. Each channel must complete in 8 us or it will timeout: NOTE: If a timeout occurs, the PCIM bus will no longer be functional. The value of these signals can be written/read by S/W in the instance. Because of the shared DMA/PCIS interface, this maps to the same address space exposed by the AppPF BAR4 address. Note there is a 16 deep clock crossing FIFO between the Timeout Detection block and the CL logic. The Management PF is persistent throughout the lifetime of the instance, and it will not be reset or cleared (even during the AFI Load/Clear process). This means write data will be accepted and thrown away, and default data (0xffffffff) will be returned for reads. In future revisions of the HDK, AWS scripts may override the cl_sh_id0/id1 to include an integrity hash function. first_be : 4’b1110 Refer to the, The SDA Interface is an AXI-Lite interface associated with MgmtPF and BAR4.
