TMS320C6415: Recommendation for TMS320C6415E / TMS320C6655 Migration to Next-Generation TI Processor (ARM + DSP Platform)

Hello TI Team,

We are evaluating processor options for a long-term redesign of a legacy DSP-based signal processing platform.

Existing Hardware

Our current design includes:

• TMS320C6415E DSP-based processing boards
• TMS320C6655/C66x DSP-based processing boards
• FPGA-connected high-speed acquisition architecture
• Multiple DSPs performing real-time signal-processing algorithms
• Ethernet-based host communication
• Inter-board communication between processing modules

We have reviewed the 66AK2H06 (Keystone II) EVM as a possible migration candidate and would appreciate TI's guidance on the most suitable long-term replacement platform.

System Requirements

We are looking for an SoC with the following capabilities:

Processing

• ARM + DSP heterogeneous architecture
• Approximately 8 ARM cores (or equivalent processing capability)
• C66x/C7x DSP support preferred
• Real-time deterministic signal processing
• Long-term TI support roadmap

FPGA Connectivity

• High-speed FPGA interface options
• PCIe preferred
• Alternative recommendations are welcome

Network Connectivity

• Dual Gigabit Ethernet ports minimum

Inter-Board Communication

Please recommend the most suitable interface among:

• SRIO
• PCIe
• Ethernet
• Other high-performance alternatives

Memory

• DDR3/DDR4/LPDDR support
• Large memory space for high-speed acquisition and buffering

Current Architecture

Our current systems use:

Our internal evaluation shows migration paths involving Keystone-II and newer Jacinto devices. We would like TI's recommendation on the preferred long-term platform. Our current designs use FPGA connectivity, DDR memory, and Ethernet communications, while newer architectures have already moved from older PCI-based approaches toward Ethernet and FPGA-centric designs.
