This document describes system design considerations for the TMS320C6455 (C6455). It also gives comparisons to designing with the TMS320C6416T (C6416T) for those familiar with that device. The objective of this document is to cover system design considerations for the C6455. Those familiar with the C6416T can use the comparisons to migrate a C6416T design to the C6455. In some cases there is infor
This document describes the GSM full-rate voice coding implementation on the TMS320C62xx processor (also called the vocoder). It discusses the system requirements and is designed for programmers who want to use the code in a basic GSM architecture.
This application report describes how the TMS470 high-end timer (HET) peripheral can be used to implement multiple additional full-duplex high-speed universal asynchronous receiver transmitter (UART) interfaces with interrupt capability and zero ARM7 CPU overhead. The solution is provided for both TMS470R1A256 and TMS470R1B1M devices but the information applies to other TMS470 family members as w
The Near Field Communication (NFC) market is emerging into multiple fields including Medical, Consumer, Retail, Industrial, Automotive and Smart Grid. Card Emulation is one of the three operational mo
This application report describes a method to dynamically increase device frequency in a way that minimizes voltage dips on the board power supply. The PLL’s multiplier can be stepped in 8% steps every 50 reference clocks.
This application note steps through the rework process to convert the TPS2413EVM, HPA227-002, to demo the TPS2419. There is no dedicated EVM for TPS2419.
This application report describes the development of a new low power binaural wearable digital hearing aid platform based on the TMS320C5000(tm) fixed point digital signal processor(DSP). This platform is a real-time system capable of processing two input speech channels at a 32 KHz sampling rate for each channel and driving a stereo headphone output. It provides for frequency shaping noise suppr
This article discusses the thermal noise source of electrocardiogram (ECG) applications basedon the ADS1298 and ADS1298R family of multichannel simultaneous sampling 24-bit delta-sigma (ΔΣ) analog-to-digital converters (ADCs). This report offers several observations on identifying the major sources of thermal noise in an ECG system and makes several recommendations regarding how to improve t
This application report presents a comprehensive collection of the input and output characteristic curves of integrated circuits from various 5-V logic families. These curves go beyond the information given in data sheets by providing additional details regarding the characteristics of the components. This knowledge is particularly useful when for example a decision must be made as to which circ
