The Valgrind distribution has multiple tools. The most popular is the memory checking tool (called Memcheck) which can detect many common memory errors such as: * touching memory you shouldn t (eg. overrunning heap Block boundaries) * using values before they have been initialized * incorrect freeing of memory, such as double-freeing heap Blocks * memory leaks.

This a software runing on the matlab, it is used in the channel coding simulation. It include DVB-S2 LDPC, Covolution turbo, and Block turbo code, You can choose which channel coding to run. it run the encoder and add white noise in the channel, then it run the decoder, and compute the error rate.

USB海量存储设备类规范包括四个独立的子类规范:(ATA command的那个没有) ①USB Mass Storgage Class Control/Bulk/Interrupt(CBI)Transport ②USB Mass Storage Class Bulk-Only Transport ③USB Mass Storage Class ATA Command Block ④USB Mass Stroage Class UFI Command Specification。 前两个子规范定义了数据/命令/状态在USB上的传输方法。 Bulk-Only传输规范仅仅使用Bulk端点传送数据/命令/状态, CBI传输规范则使用Control/Bulk/Interrupt三种类型的端点进行数据/命令/状态传送。 后两个子规范定义了对存储介质的操作命令。 ATA 命令规范用于硬盘。 UFI命令规范是针对USB移动存储而制定的,实际上UFI命令格式是基于SFF-8070i和SCSI-2规范,总共定义了19个12字节长度的操作命令。

Verilog and VHDL状态机设计,英文pdf格式 State machine design techniques for Verilog and VHDL Abstract : Designing a synchronous finite state Another way of organizing a state machine (FSM) is a common task for a digital logic only one logic Block as shown in engineer. This paper will discuss a variety of issues regarding FSM design using Synopsys Design Compiler . Verilog and VHDL coding styles will be 2.0 Basic HDL coding presented. Different methodologies will be compared using real-world examples.

This paper investigates the design of joint frequency offset and carrier phase estimation of a multi-frequency time division multiple access (MF-TDMA) demodulator that is applied to a digital video broadcasting—return channel system via satellite (DVB-RCS). The proposed joint estimation algorithm is based on the interpolation technique for two correlation values in the frequency and phase domains. This simple interpolation technique can significantly improve frequency and phase resolution capabilities of the proposed technique without increasing the number of the correlation values. In addition, the overall Block diagram of a digital communications receiver for DVB-RCS is presented, which was designed using the proposed estimation algorithms. Index Terms—Carrier phase estimation, DVB-RCS, frequency offset estimation, interpolation, joint estimation, MF-TDMA.
