Because SDRAM is used, first we add a PLL
Input clock 50 MHz
The output clock C0 is 50 MHz and the phase is-75 degrees. The clock is provided to the SDRAM and the pin is named sd_clk.
C1 50nhz, with a phase of 0 degrees. It provides a clock signal to the nioss-clk and is connected to the nioss-clk.
1. enable the system file system, add the CPU, and select the system file system.
2. Add SDRAM, se
Expression Design is a member of the Expression series and a good helper for Blend and Web.
In this chapter, I will introduce the basic interface of Expression Design 4.
After enabling Expression Design 4, I believe that a friend who has used Adobe-related multimedia tools should have a similar Fu on the Design interfaces and tools...
Yes. If you are familiar with Adobe-related multimedia tools, it will be easy to use Design.
Because many shortcut keys in Design are almost the same as those in
Today I have studied how to modify preset objects in batches. project requirements must be studied ~~

Cmd-space: The Language System Used for switching (if more than one language system is installed ). Opt-F3, opt-F4, or opt-F5 enables the system presets window for Mac OS X (only when system presets are not executed ). The cmd-F1 detects the monitor in Mac OS X.
