"The input clock source to the DSP can be directly used to generate the clocks to other parts of the system (Bypass Mode) or it can be multiplied by a value from 2 to 15 and divided by a value from 1 to 32 to achieve a desired frequency (PLL mode ). the pllen bit of the PLL control/Status Register (pllcsr) is used to select between the PLL and bypass modes of the clock generator."

From the above description, we can see that t
DSP, DSW, NCB, opt, CLW, PLG, and APS files are respectively stored in what stuff, what is the role?
From VC ide tips:------------------------------The parameter file of the OPT project on the development environment. Such as the tool bar position and other information;
. APS (appstudio file), Resource auxiliary file, binary format, usually don't worry about it.
. The CLW classwizard information file is actually in the INI file format. If you ar
operation of fixed-point number is simpler and more efficient in the computer, while the operation of floating-point numbers is more complex and less efficient in computer.
(3) Hardware dependencies
In general, as long as the hardware to provide operational components, will provide fixed-point operation support (do not know the exact number, did not have heard of no support fixed-point operation of the hardware), but not necessarily support floating-point operations, such as many embedded dev
Main Features:
1. Smaller size2, the interface is more secure3, more Outstanding performance4, speed is one times faster than other simulators
· Using high-speed version USB2.0 standard interface, Plug and Play, transmission speed up to 480MBS, backward-compatibleUSB1.1 host;
· Standard JTAG emulation interface, does not occupy the user resources; Special interface security design, fully support JTAG interfaceHot Plug and pull;
· Support WINDOWS98NT2000XP operating system;
· Support Ti ccs2

We know that after the DSP starts, the system will enter the reset interrupt, at this time the Reset interrupt service function is c_init00, this function is used to establish the C environment, to enter the main () function for system initialization, the main work is to build the stack, initialize the global variables and so on.
Initialization of global variables: If the program is linked with the-C option, the compiled linked executable will place
flash, follow these steps:1) Add the boot. ASM Program to the user program, and the address space is allocated as 0x00 ~ 0x400;2) Compile the CMD file for hex conversion.3) use the hex6x tool to convert the out file into a hex binary file.4) use flashburn to write it to flash.
2. In the ccs3.3 environment, use the seedconverttool for file conversion.The procedure is as follows (the customer represents the customer's application name ):1) design the customer application to generate the customer.
EDMA event and the channel (some DSP models are fixed mappings);
PQSR: Indicates the state, indicating whether the transmit register is empty at each priority level;
CIPR: Indicates the channel interrupt pending state;
CIER: To enable or shield the channel to interrupt;
CCER: To enable or shield the channel chain;
ER: Represents a state that represents a captured event;
EER: Enable or mask every event in ER;
ECR: Clears events that have been triggere

Environment
Operating System: win7, 64bit
IDE: CCS v3.3
Simulator: Seed xds510plus
DSP model: tms320c6713gdp (dsp6713)
Check Procedure
Try to press the reset button and then click Connect connection
Check whether the power supply is normal (whether the core voltage is 1.2 V, and whether the I/O port voltage is stable at 3.3 V)Use the oscilloscope AC to test and check the ripple of the power supply. Page 99 of the tms320c6713 Data Manual requir
In the case of code maintenance, the CPU accesses the external memory space 0x75510c55 address of the COREPAC, that is, the CPU initiates access to that memory to the L2 memory controller of COREPAC, and then L2 the memory controller sends the request to Corepac's XMC module. XMC module According to the configured register (that is, 32bit virtual address to 36-bit physical address mapping and memory rights register, each memory segment size 16M with a register set, each CPU has the same number o
