Vivado HLS工具提取的案例研究2:稀疏矩阵向量乘法 附加并行性显然不足以补偿硬处理器内核对于稀疏矩阵向量(SpMV)乘法是一个可编程逻辑的时钟频率优势计算内核,已经在各种研究项目中以很多不同方法进行过研究、变换和基准确定。这里,我们的目的不是以及来自可重配置阵列的使用特殊数据结构和存储分配方式更长的数据访问时延...
下面是一个具有两个通道的HBM上的CPSR示例,目标是用于SpMV的4-PE加速器: Accelerator Architecture 对于每个HBM通道,实例化一个PE群以饱和内存带宽。每个PE都是一个三阶段的管道:从输出缓冲区读取值,更新结果,并写回更新后的值 Runtime Support. GraphLily构建了一层中间件,简化了加速器的编程。中间件将每个加速器...
Design.Sparse Matrix-Vector Multiplication (SpMV) is an important core kernel used in many scientific applications. SpMV is a communication-bound algorithm that suffers poorly from spatial locality. It exhibits low computation-tocommunication ratio due to its inherent irregular memory access patterns. ...
AXIS 接口只能分配给内核或 IP 的顶层实参(端口),不能分配给设计内部函数实参。HLS 设计内部使用的串流通道应使用 hls::stream,而不能使用 AXIS 接口。ap_axis 结构体支持您选择接口实现(含旁路或不含旁路),不含旁路通过使用更少的资源来将 AXIS 接口实现为超轻量级接口,含旁路实现全功能接口以提供更强大的控制...
The numbers are: pre-processing time, SpMV run time, SpMV data throughput, SpMV operation throughput. Note: data throughput = operation throughput / 2 * 8. 5. Build and run the design cd sw make benchmark IMPL=<fixed/float_pob/float_stall> The IMPL option is used to switch between th...
