Synchronous DRAM (SDRAM) has become a mainstream memory of choice in embedded system memory design due to its speed, burst access and pipeline features. For high-end applications using processors such as Motorola MPC 8260 or Intel StrongArm, the interface to the SDRAM is supported by the processor’s built-in peripheral module.

This VHDL code takes a clock, reset, Capture_EN and SPI data LT2315 ADC and generates SPI_CLK and SPI_nCS of it and reads 12-bit serial data ADC and returns 12-bit parallel data.

axi协议中的full子协议，可用于直接访问zynq器件的ddr器件。(The full sub protocol in the Axi protocol can be used to direct access to the DDR device of the zynq device.)

Once the FPGA is located, the rest of the mapping data for the other components can be determined dynamically its section mapping registers.
