This application report discusses the power consumption of the Texas Instruments TMS320C6455 and TMS320C6454 digital signal processor (DSPs). The power consumption on the C645x devices is highly application-dependent, therefore, a power spreadsheet that predicts power consumption is provided along with this application note. The power spreadsheet can be used for the purpose of modeling power consu

This application report contains implementation instructions for the DDR2 interface contained on the TMS320C6454/5 digital signal processor (DSP) device. The approach to specifying interface timing for the DDR2 interface is quite different than on previous devices.The previous approach specified device timing in terms of data sheet specifications and simulation models. The system designer was

The C64X+ Megamodule supports a wide variety of internal memory configurations by allowing the L1 program and data memory (L1P and L1D) to set as cache only, SRAM only, or a mixture of cache and SRAM. In addition, the C64x+ Megamodule provides new system functionality including: cache freeze, Internal DMA (IDMA), bandwidth management, and memory protection. This document discusses the enhancements

This application report describes the error detection and correction mechanism of the C64x+/C674x megamodule L1P and L2 memories implemented on some devices. Depending on the type of application, these mechanisms are used to either provide diagnostic measures to detect faults in the memory that could lead to unacceptable risk for the user or to increase the availability of the system.

This application report motivates the way the DDR high-speed timing requirements are now going to be communicated to system designers. The traditional method of using data sheet parameters and simulation models is tedious. The system designer uses this information to evaluate whether timing specifications are met and can be expected to operate reliably.Ultimately, the real question the hardwa

This document describes migration from the Texas Instruments TMS320C64xв„ў digital signal processor (DSP) to the TMS320C64x+в„ў DSP. The objective of this document is to indicate differences between the two cores and to briefly describe new features. Functionality in the devices that is identical is not included. For detailed information about either device, see the TMS320C64x/C64x+ DSP

The TMS320C6000™ Digital Signal Processors (DSPs) have many architectural advantages that make them ideal for computation-intensive real-time applications. However to fully leverage the architectural features that C6000™ processors offer code optimization may be required. First this document reviews five key concepts in understanding the C6000 DSP architecture and optimization. Then
