This book enunciates and illustrates features and basic principles of C++. It
is aimed at experienced C users who wish to learn C++. It can also be
interesting for beginner C++ users who leaved Out some possibilities of the
language.
FIFO電路(first in,first Out),內部藏有16bit×16word的Dual port RAM,依次讀出已經寫入的數據。因為不存在Address輸入,所以請自行設計內藏的讀寫指針。由FIFO電路輸出的EF信號(表示RAM內部的數據為空)和FF信號(表示RAM內部的數據為滿)來表示RAM內部的狀態,并且控制FIFO的輸入信號WEN(寫使能)和REN(讀使能)。以及為了更好得控制FIFO電路,AEF(表示RAM內部的數據即將空)信號也同時輸出。
This device driver implements KMDF based virtual bus driver and generic virtual disk hosted on it. Users can add virtual disks to Windows OS which are then seen and managed by OS as generic, regular disks. Virtual disks are plug in/Out with cmdln utility.
These templates are based on the documented Outlines from Tim Ryan s "The
Anatomy of a Design Document" articles (published on Gamasutra). The filler
text comes straight from the articles, and have been slightly edited for
clarity (and to use the British spelling NMP).
To read the articles (which I would highly suggest), check Out these links:

The first task at hand is to set up the endpoints appropriately for this example. The following code switches the CPU clock speed
to 48 MHz (since at power-on default it is 12 MHz), and sets up EP2 as a Bulk Out endpoint, 4x buffered of size 512, and EP6
as a Bulk IN endpoint, also 4x buffered of size 512. This set-up utilizes the maximum allotted 4-KB FIFO space. It also sets up
the FIFOs for manual mode, word-wide operation, and goes through a FIFO reset and arming sequence to ensure that they are
ready for data operations
基于OFDM的無線寬帶系統仿真It contains mainly two parts, i.e. link-level simulator and system-level simulator.
Link-level simulator focus on a single-cell single-user scenario, where signal is transmitted from tx, and estimated at rx. Comparing the difference in tx/rx signal, the error rate can be found Out. The Output of the link-level simulator is the BLER/BER vs. SNR mapping table, that can be used for the system-level simulation.
System-level simulator focus on a multi-cell multi-user scenario. For the sake of simplicity, it takes the mapping table aquired in the link-level simulation, measure the actural SNR, and finds the corresponding error rate.
