AMBA AHB Direct Memory Acess (DMA) Controller

AMBA AHB Direct Memory Acess (DMA) Controller

Key features

  • Multiple independent DMA channels with direct AHB bus interface.
  • DMA transfers between AHB memory devices and I/O ports.
  • Scatter-gather allows DMA to merge multiple data source to contiguous space.
  • Supports both hardware initiated transfer and software initiated transfer.
  • Supports burst transfer to maximize data bandwidth.
  • Automatic address increment or decrement.
  • Interrupt generation on transfer completion.
  • Burst data access on the AHB interface and user I/O interface.
  • Handles wait state insertion by any slave devices.
  • Supports all slave device responses: OKAY, RETRY, SPLIT and ERROR.
  • Master does not insert wait state on AHB bus thus maximize data bandwidth.
  • No delay insertion on data transfer between user I/O interface and AHB bus.
  • Separate user interface for DMA control register programming.
  • User interface matches seamlessly with other Eureka Technology IP cores.
  • Optimized for ASIC and PLD implementations.

Toki: Profiling HBM Performance on FPGA Systems with RISC-V Soft Cores and PCIe Host DMA Traffic

Toki, released as open source, is the first hardware-software framework that enables profiling the performance of HBM on FPGA accelerator cards by jointly considering (i) the execution of workloads on RISC-V soft cores instantiated on the FPGA and (ii) the injection of memory traffic from the host system via DMA over PCIe, providing insights that cannot be obtained with synthetic traffic generators alone.

DMA IP Integration

There are many IP’s today . These IP’s can be simple IP’s like Timer to complex IP’s like Accelerators. In Most of the cases IP’s are Integrated in standard way. There are cases where you have the option of Integrating it differently. This goes un-noticed or unable to be implemented due to time constraints. One such IP that would be discussed in this paper is DMA . This paper tries to explain idea of Integrating Direct Memory access(DMA) and Interrupt Control Unit(ICU) differently but final implementation requires some changes in IP. There is a possibility that alternate design explained below may be already implemented.
