Tips for Using the EDMA with the Utopia Port
Texas InstrumentsTypically the EDMA services the UTOPIA interface by writing data to the slave transmit queue (UXQ) and reading data from the slave receive queue (URQ). This document discusses the proper way to configure the EDMA to interface with the UTOPIA port by:
- Describing the EDMA configuration required to complete a 2D array synchronized transfer to UTOPIA.
- Giving three possible soluti

Using TMS320C6416 Coprocessors: Turbo Coprocessor (TCP) (Rev. B)
Texas InstrumentsThe turbo coprocessor (TCP) is a programmable peripheral for decoding IS2000/3GPP turbo codes that are integrated into the Texas Instruments (TI™) TMS320C6416 digital signal processor. The TCP is controlled via memory-mapped control registers and data buffers. Control registers can be accessed directly by the CPU whereas data buffers are typically accessed using the EDMA controller. This a

Using the TPS5430 As An Inverting Buck Boost Converter (Rev. A)
Texas InstrumentsThe wide input voltage range SWIFT™ dc/dc converters are used typically as step-down converters where the derived output is a positive voltage less than the input voltage source. In some cases it may be required to generate a negative voltage from the input voltage source. In such instances it is possible to configure the TPS5430/20/10 devices in an inverting buck-boost topology where the outpu
Wave Digital Filtering Using the MSP430
Texas InstrumentsDigital filtering is an integral part of many digital signal processing algorithms. Digital filters are characterized as either recursive [infinite impulse response (IIR)] or non-recursive [finite impulse response (FIR)] filters. IIR filters require a smaller order for the same set of specifications compared to FIR filters, while FIR filters provide a linear phase property. However, IIR filters, if not designed properly, tend to be unstable and use coefficients that are difficult to implement. This application report discusses the design of a certain type of IIR digital filter with excellent stability properties, known as a Lattice Wave Digital Filter (LWDF), given a set of analog filter specifications. An elementary knowledge of filters is sufficient to understand the design of LWDF as discussed in this report. The complete design of the basic filters (low-pass, high-pass, and band-pass) is given with examples. Code that implements these LWDFs on the MSP430 CPU is provided with this report.
