<strong>10</strong>.2 SDRAM Controller (SDRC) <strong>Subsystem</strong><br />

This section describes the SDRAM controller (SDRC) subsystem.<br />

<strong>10</strong>.2.1 SDRC <strong>Subsystem</strong> Overview<br />

The SDRC subsystem module provides connectivity between the device POP-ed SDRAM memory<br />

components. The module includes support for low-power double-data-rate SDRAM (LPDDR1).<br />

The SDRC subsystem provides a high-performance interface to a variety of fast memory devices. It<br />

comprises two submodules:<br />

• The SDRAM memory scheduler (SMS), consisting of scheduler and virtual rotated frame-buffer (VRFB)<br />

modules<br />

• The SDRC<br />

CAUTION<br />

DDR SDRAM and SDR SDRAM memory types cannot be connected<br />

simultaneously to the SDRC memory interface.<br />

Figure <strong>10</strong>-41 shows the SDRC subsystem environment.<br />
