Multi-Channel SAE-J2716 (SENT) Decoder Using NHET
Texas InstrumentsThe SAE-J2716 standard is a product of the Data Communications Standards Committee under the Electrical Systems Group of the Motor Vehicle Council. This is the same committee that has produced standards for the widely adopted SAE-J1850, CAN, and LIN protocols. This application report provides an example of how the TMS570 NHET v2 may be used to implement a decoder for the SAE-J2716 (Feb 2008) protocol standard; the decoder presents the data and eliminates the need for CPU to do it. (Note that the standard has been updated again in Jan 2010 but not covered by this application note).
TMS320C64x EDMA Architecture
Texas InstrumentsThe enhanced DMA (EDMA) controller of the TMS320C64x™ device is a highly efficient data transfer engine. To maximize bandwidth minimize transfer interference and fully utilize the resources of the EDMA it is crucial to understand the architecture of the engine. Transfer requests (TRs) originate from many requestors including sixty-four programmable EDMA channels the level 2 (L2) memory
Modified Goertzel Algorithm in DTMF Detection Using the TMS320C80 DSP
Texas InstrumentsThis document presents a modified Goertzel algorithm for DTMF tone detection on a TMS320C80 ('C80) 32-bit multiprocessor digital signal processor (DSP). The algorithm detects the incoming frequency with an offset range plus or minus 1.5%. For this application a basic implementation is provided but additional testing is required to make this detection algorithm complete. The appendix provides the

Digital Monopulse Doppler Radar and DSP Teaching
Texas InstrumentsIn 1995 several teams of EFREI students submitted a project to the Texas Instruments DSP Challenge. This paper describes the adventure of one project which passed with success the European semi-finals to go and participate to the worldwide final in May 1996 in ATLANTA.The winning project deals with the Digital Signal Processing (hardware and software) associated with a new class of a Digital
Intel StrataFlash Embedded Memory (P30) Power Solutions
Texas InstrumentsThis application report provides several recommended power management solutions for the Intel™ StrataFlash™ Embedded Memory (P30). Intel has migrated from its third-generation 180-nm J3 process to its fourth-generation 130-nm P30 process on flash memory and will be discontinuing the older J3 256-Mb memory. Migrating from J3 memory to the P30 Embedded Memory allows systems to operate at

Fast Settling Low-Pass Filter
Texas InstrumentsNoise reduction by filtering is the most commonly used method for improving signal-to-noise ratio. The increase in settling time however can be a serious disadvantage in some applications such as high-speed data acquisition systems. The nonlinear filter described here is a simple way to get a four-to-one improvement in settling time as compared to a conventional filter.
Interfacing the DAC8806 and DAC8820 to TMS320 DSPs
