TMS320DM8127BCYE3

Digital Signal Processor Dsp Overview

The TMS320DM8127BCYE3 is a high-performance System-on-Chip (SoC) from Texas Instruments, part of the DaVinci video processor family. It integrates an ARM Cortex-A8 core operating up to 750 MHz and a C674x VLIW DSP running at 750 MHz. The device features a dedicated HD Video Processing Subsystem (HDVPSS) with capture and display interfaces, including HDMI 1.3 output. Key specifications include 256 KB of L2 cache for both processors, dual 32-bit DDR2/DDR3 memory controllers supporting up to 2 GB total address space, and extensive peripherals such as Gigabit Ethernet, USB 2.0, PCIe 2.0, and six UARTs. Manufactured using 45-nm CMOS technology, it utilizes a 684-pin Pb-free BGA package.

Digital Signal Processor Dsp Feature Summary

• Dual-core architecture combining an in-order ARM Cortex-A8 RISC core and a floating-point C674x VLIW DSP.
• Integrated HD Video Processing Subsystem (HDVPSS) supporting one 165-MHz HD capture input and two 165-MHz display outputs.
• Imaging Subsystem (ISS) featuring Image Sensor Interface (ISIF), Image Pipe (IPIPE), Resizer, and Hardware 3A Engine.
• Extensive connectivity including Dual Port Gigabit Ethernet, Dual USB 2.0 ports, PCIe 2.0 x1, and multiple serial interfaces.

Digital Signal Processor Dsp Applications

Digital Signal Processor Dsp Procurement Notes

Verify the specific suffix 'BCYE3' against the manufacturer's current product selection guide to confirm availability status and exact pinout compatibility. Ensure that the required DDR2 or DDR3 memory components are JEDEC compliant and match the supported speed grades specified in the datasheet electrical characteristics section.

Digital Signal Processor Dsp Selection Notes

Select this component when a mixed-processor solution requiring simultaneous real-time video processing and complex system control is necessary. Consider the 256 KB L2 cache limitation compared to higher-end models like the DM8148 if larger on-chip memory is required. Verify that the application environment supports the 45-nm process thermal requirements and the specific power-up sequencing defined for the multiple voltage domains.

Digital Signal Processor Dsp Part Context

This device belongs to the TMS320DM812x series within the DaVinci Digital Media Processor portfolio. It shares architectural similarities with the TMS320DM8148 but lacks the SATA interface and SGX530 graphics engine found in the latter. The BCYE3 designation indicates a specific temperature range and package variant within the CYE (684-pin BGA) family.

Digital Signal Processor Dsp Replacement Considerations

TMS320DM8148CCYE3: Offers increased L2 cache (512 KB) and integrated SATA, but lacks the Face Detect engine present in the DM8127.
