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 R2.9 revision of the CLID detector provides the TYPE 1 (on-hook, between first and second ring, or
before first ring) signal detection and returns the message raw byte data without parsing of particular fields
such as Message Type, Parameter(s) Type(s), etc. The decoding of the message meaning should be performed by the user application.主叫號碼識別CID算法for TI DSP
The algorm of viterbi. You talk to your friend three days in a row and discover that on the first day he went for a walk, on the second day he went shopping, and on the third day he cleaned his apartment. You have two questions: What is the overall probability of this sequence of observations? And what is the most likely sequence of rainy/sunny days that would explain these observations? The first question is answered by the forward algorithm the second question is answered by the Viterbi algorithm. These two algorithms are structurally so similar (in fact, they are both instances of the same abstract algorithm) that they can be implemented in a single function:
This file contains the material presented as the first Embedded MATLAB webinar on the MathWorks web site on September 13, 2007.
It contains the PDF version of presentation slides and all necessary demonstration files (including MATLAB M-files and Simulink models).
This document represents the first stage in a process of taking the National Strategy for Police Information Systems (NSPIS) forward. It defines the mechanisms to ensure that we (and our partners) have access to the right information, in the right form, in the right time at an appropriate cost. The Strategy will ensure the Police Service has a collective understanding of the value of information and that we are able to exploit National Information Assets in support of local policing.
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
Compile SQLite using the cross-compiler such as arm-linux-gcc
first, get sqlite-3.3.6.tar.gz from www.sqlite.org
unzip it,
#tar -zxvf sqlite-3.3.6.tar.gz
change into the sqlite-3.3.6 directory
cd sqlite-3.3.6
