Digital Signal Processor Dsp Procurement Notes

Verify the ordering suffix 'CUN' corresponds to the specific 561-pin FBGA package dimensions and ball pitch required by the design. Confirm that the selected frequency grade (e.g., 1.2 GHz) matches the thermal management capabilities of the target system, as higher speeds may require heatsinks to maintain operation within the specified temperature range.

Digital Signal Processor Dsp Selection Notes

Select the appropriate speed grade based on real-time processing requirements; the 1.2 GHz variant offers the highest performance but operates within a 0°C to 95°C commercial temperature range. Ensure the design supports the required SmartReflex adaptive voltage scaling for the 0.9-V to 1.2-V core voltage. Verify compatibility with existing development tools, such as the C compiler and debugger, for code migration from previous C6000 platforms.

Digital Signal Processor Dsp Part Context

This component belongs to the TMS320C64x+ family, representing the third-generation high-performance VelociTI architecture. It serves as a successor to single-core C64x devices, providing upward code compatibility while significantly increasing throughput through multicore integration and enhanced peripheral sets like the EDMA3 controller and DDR2 memory interface.

Digital Signal Processor Dsp Replacement Considerations

Direct pin-to-pin replacements are limited within the same package family. Consider the TMS320C6474 variants with different speed grades (e.g., GUN, ZUN suffixes) if frequency or temperature specifications differ. For legacy upgrades, evaluate migration paths from C64x single-core devices, noting architectural differences in cache and peripheral availability.

Digital Signal Processor Dsp FAQ

What is the maximum clock frequency for the TMS320C6474FCUNA2?

The device supports clock rates up to 1.2 GHz, with corresponding instruction cycle times of 0.83 ns. Lower speed grades of 1 GHz and 850 MHz are also available depending on the specific part number suffix.

Does the TMS320C6474 support floating-point operations?

No, the TMS320C6474 is a fixed-point digital signal processor. It utilizes the C64x+ architecture optimized for integer arithmetic, including 16-bit, 32-bit, and 64-bit data types, but does not include a hardware floating-point unit.

How many Serial RapidIO links are integrated into this device?

The TMS320C6474 integrates two 1x Serial RapidIO links compliant with version 1.2, supporting link rates of 1.25, 2.5, or 3.125 Gbps for point-to-point inter-device communication.
