1.1.4 High-Performance Memory Subsystem

The following list provides the characteristics of the high-performance memory subsystem:

  • 64 KB embedded SRAM (eSRAM)
  • Up to 512 KB embedded Non Volatile Memory (eNVM)
  • One Serial Peripheral Interface (SPI)/Communication Block (COMM_BLK)
  • DDR bridge (2 port data R/W buffering bridge to DDR memory) with 64-bit AXI interface
  • Non-blocking, multilayer AHB bus matrix allowing multi-master scheme supporting 5 hosts and 7 clients
  • Two AHB/Advanced Peripheral Bus (APB) interfaces to FPGA fabric (host/client capable)
  • Two DMA controllers to offload data transactions
    • 8-channel Peripheral DMA (PDMA) for data transfer between HPMS peripherals and memory
  • High-Performance DMA (HPDMA) for data transfer between eSRAM and DDR memories
