It also shows how a hardware is mapped on the CLB resources and how a C program can be used to describe a circuit. An HLS tool transforms the C source code into an intermediate code in VHDL or Verilog and a placement and routing tool builds the bitstream to be sent to configure the ...
Many FPGAs use 4-input LUTs which can be configured to implement any 4-input logic function. In order to better support the wide data paths employed in some applications, some FPGAs offer 6, 7, or even 8-input LUTs. The output from the LUT is directly connected to one of the logic ...
High-Level Synthesis (HLS) extends the traditional design flow, providing a new and powerful approach to hardware design. It is important to understand the fundamentals of HLS and how HLS bridges the gap between the RTL designer and architect, and functional verification and RTL verification. This...
There is a clock synchronous with the data at 2.8GHz DDR. After many months of work, I have come to the conclusion that there is absolutely no way that any FPGA can handle this as the data is unencoded, NRZ, and no internal/external memory element...
这些HLS工具的构成与传统编译器类似,分别为前端、中端与后端。前端负责解析高层次语言与设计参数,生成抽象语法树(AST, Abstract Syntax Tree),转化为IR。中端主要负责对IR、CDFG的一些与硬件相关的优化,例如位宽缩小、强度弱化(例如乘法变成加分移位)、分支融合、死代码消除、循环展开等等,目标是提高硬件时空并行度、...
1.Since the FPGA knows to read configuration data from 0x400000, shouldn't the value of this address be stored somewhere? And it will not be lost after power off, is there a corresponding non-volatile register inside the FPGA to save the starting address ...

you compile it into an HLS tool like C-to-Silicon Compiler and begin exploring the solution space. In a typical flow, you might have the tool schedule the design as-is so you can explore how resources were mapped, where your critical timing/area/power issues are, a...
