This glossary is a collection of the definitions of Texas Instruments' Delta-Sigma (ΔΣ), successive approximation register (SAR), and pipeline analog-to-digital (A/D) Converter specifications and performance characteristics. Although there is a considerable amount of detail in this document, the product data sheet for a particular product specification is the best and final reference.
The 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).
The 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 controller, and other master peripherals. The EDMA controls access to resources and arbitrates between concurrent transfers. Understanding the interaction points for transfer requests in the EDMA architecture is crucial to creating a system that takes full advantage of EDMA’s capabilities.
