Bit-Reversed Addressing Without Data Alignment on the TMS320C3x
Texas InstrumentsBit-reversed addressing mode normally requires that the n-element array be aligned on an n-word boundary. When n is large this may result in a large hole in the memory map. To enable more efficient use of memory a technique to use bit-reversed addressing without data alignment is presented.
DN-56A, Single Switch Flyback Circuit Converts + 5 V to +/- 12 V for RS-232/422
Texas InstrumentsA bipolar 12V supply from a single +5V input can be developed using a number of conventional approaches. A boost converter is the most logical for the +12V output; however, it cannot be used in some i
Migrating CCS 1.20/CCS 1.0 Projects to CCS 2.0 (Rev. A)
Texas InstrumentsThis application report describes the process of migrating an existing Code Composer Studio?(CCS) version 1.x (v1.x) project to a CCS v2 project.
Interfacing the TMS320C54x DSP to the TLC320AD535 /545 Codecs
Texas InstrumentsThis application report presents a method for interfacing the TLC320AD535 and TLC320AD545 codecs from Texas Instruments (TI)(tm) with the multichannel buffered serial port (McBSP) on TI's C54xx family of digital signal processors (DSPs). As is the case with many codecs from TI these devices utilize a primary and secondary communication protocol to differentiate between actual signal data and code
Choosing the Right TPS6420x Buck Controller
Texas InstrumentsThis application note provides a table to aid in selecting the right TPS6420x option for your application.
TMS320C40 DMA Memory Transfer Timing
Texas InstrumentsThis document discusses how many cycles it takes the DMA to read/write to external memory. Several tables are given to allow the developer to determine this information for several different types of configurations.
Monitoring TMS320C240 Peripheral Registers in the Debugger Software
Texas InstrumentsThis document discusses how to view the peripheral registers on a 'C240 or 'F240 device while running the emulator. It includes a lengthy code example.
Interfacing the ADS7881 to TMS320C6713 DSP
Texas InstrumentsThis application report presents a solution to interfacing the ADS7881 12-bit parallel interface converter to the TMS320C6713 DSP. The hardware solution is made up of existing hardware specifically the ADS7881EVM 'C6713 DSK and the 5-6K Interface Board. The software demonstrates how to use an EDMA ping-pong buffer and Timer1 peripherals to collect data at 4 MSPS. Discussed also are some of the

TMS320DM64x Power Consumption Summary (Rev. F)
Texas InstrumentsThis document discusses the power consumption of the Texas Instruments TMS320DM640 TMS320DM641 TMS320DM642 and TMS320DM643 digital signal processors (DSPs). Power consumption on these devices is highly application-dependent so a spreadsheet is provided to model power consumption for a user's application. To get good results from the spreadsheet realistic usage parametersmust be entered. T
TLV320AIC3104 Programming Made Easy
Texas InstrumentsThe TLV320AIC3104 (AIC3104) is a versatile audio codec with multiple features. When first designing with the AIC3104 reading the entire data sheet and becoming familiar with the entire register set can be a daunting task. However in many common configurations it is possible to get the AIC3104 up and running while only writing to as few as 12 registers.Although not intended to replace the da
How to Begin Development Today With the TMS320C6211 DSP
Texas InstrumentsDevelopment may begin now for TMS320C6211 systems. Due to the compatibility between TMS320C6000 generation devices current 'C6000 tools may be used to develop code for the 'C6211 and other future devices. This allows for systems to be up and running when silicon becomes available.
A Power-Distribution Switch With Latched Over-Current Protection (Rev. A)
Texas InstrumentsPower-distribution switches like the TPS203x operate in retry mode in an overload but some applications require the switch to latch off. The latch-off function can be implemented using the simple circuit described in this application report.
