Local memory interface
The LMI is a 16-bit wide SDR/DDR SDRAM interface with a peak bandwidth of 532 Mbyte/s
(DDR running @166 MHz). It supports 64-MBit, 128-Mbit, 256-Mbit, or 512-Mbit SDRAM.
The LMI provides a fully cacheable address space for data and instructions, with data
cacheability controlled in 512 Kbyte blocks for up to 8 Mbytes.
Flash memory interface
The FMI provides a glueless interface to SRAM, flash, SFlash and peripherals, in up to four
configurable banks over a 16-bit wide interface. Bus cycle strobe timings can be
programmed from 0 to 15 phases for slower peripherals.
Support is provided for control of DVB-CI and ATAPI connection.
Transport stream processing
The STi5107 supports single transport stream input.
It is possible to support DVB-CI configurations as shown in
Figure 4.
