RAM Block Description
General Description
The QuickSD device includes multiple dual-port 2,304-bit RAM modules for implementing
RAM and FIFO functions. Each module is user-configurable into four different block
organizations. Modules can also be cascaded horizontally to increase their effective width or
vertically to increase their effective depth as shown in the following figure. The RAM can also
be configured as a modified Harvard Architecture, similar to those found in DSPs.
