CSI Address Selectors

Provide timely, synchronous address decoding for CSL functions

CSI Address Selector

CSI Address Selector


  • Easy communication with CSL functions
    • Synchronous, timely address decoding
    • Eliminates or reduces logic overhead in CSL

  • Decode a specific address range
    • Access to a specific processor address space (code, data, SFR)
    • Address size (from 1 byte to 16 Mbytes)

  • Integrated, distributed resource
    • One CSI Selector per every 16 CSL Cells

  • Three operating modes
    • Selector decodes read and write transactions to the target address range
    • Chip Select provides a chip select (decodes both read or write) and a read/write direction control
    • DMA Control steers DMA request/acknowledge to and from a "soft" peripheral

  • Match Registers provide bit-wise decoding of the full 32-bit address space
    • Match Register values automatically assigned by the Triscend FastChip Configurable System-on-Chip Development System
