Texas Instruments TMS320DM8167SCYG4

Overview

TMS320DM8167SCYG4 from Texas Instruments is a high-performance DaVinci digital media processor integrating an ARM Cortex-A8 RISC CPU (up to 1.20 GHz), a C674x floating-point DSP core (up to 1 GHz), and three HDVICP2 video coprocessors. It delivers up to 8000 MIPS and 6000 MFLOPS, features dual DDR2/DDR3 interfaces supporting up to DDR3-1600, and targets real-time HD video encode/decode/transcode in embedded media systems.

For engineers reviewing the TMS320DM8167SCYG4 datasheet, TMS320DM8167SCYG4 pinout, TMS320DM8167SCYG4 application, or TMS320DM8167SCYG4 equivalent, key selection criteria include its triple HDVICP2 engine count, 512KB on-chip RAM, 1031-pin FCBGA package with Via Channel technology, and support for simultaneous HD/SD analog output plus HDMI 1.3 transmission.

Technical Context

The TMS320DM8167SCYG4 implements a heterogeneous dual-core architecture: the ARM Cortex-A8 handles OS execution, peripheral control, and system management using 32KB I-cache, 32KB D-cache, and 256KB L2 cache, while the C674x DSP executes computationally intensive video/audio algorithms with IEEE 754 SP/DP floating-point support and VLIW parallelism. Both cores share access to system memory via a System MMU.

Its media subsystem centers on three independent HDVICP2 engines-each capable of full 1080p60 H.264 encode or decode-and a programmable HDVPSS with dual 165-MHz capture channels, dual display channels, HDMI 1.3 transmitter with HDCP, and SD/HD DACs. The device uses 40-nm CMOS process and SmartReflex Level 2 power management across seven independent core domains.

FAQ

What is the maximum video resolution and frame rate supported by the TMS320DM8167SCYG4?

The TMS320DM8167SCYG4 supports full 1080p60 (1920×1080 at 60 fps) H.264, MPEG-2, VC-1, and MPEG-4 SP/ASP encode or decode per HDVICP2 engine. With three engines, it can concurrently process multiple 1080p60 streams-for example, encode one, decode another, and transcode a third-all in real time without CPU/DSP intervention. This capability is confirmed in the SPRS614F datasheet Section 1.1 and Figure 1-1 block diagram.

Does the TMS320DM8167SCYG4 include an integrated graphics engine like the SGX530?

No, the TMS320DM8167SCYG4 does not include the SGX530 3D graphics engine. That feature is exclusive to the TMS320DM8168 device variant, as explicitly stated in the SPRS614F datasheet Section 1.3 ("The device also includes an SGX530 3D graphics engine (available only on the TMS320DM8168 device)") and Table 3-1 Device Comparison. The TMS320DM8167SCYG4 retains full video processing capability but omits 3D rendering hardware.

What memory types and speeds does the TMS320DM8167SCYG4 support via its external interfaces?

The TMS320DM8167SCYG4 supports dual 32-bit DDR2 (up to DDR2-800) and DDR3 (up to DDR3-1600) SDRAM interfaces, delivering up to 6.4 GB/s aggregate bandwidth. It also includes a flexible 8-/16-bit GPMC for NOR Flash, NAND Flash (with BCH/Hamming ECC), SRAM, and pseudo-SRAM. These capabilities are documented in Section 1.1 Features and Table 3-2 of the SPRS614F datasheet.

How many high-definition video capture and display channels does the TMS320DM8167SCYG4 provide?

The TMS320DM8167SCYG4 provides two 165-MHz HD video capture channels and two 165-MHz HD video display channels via its HDVPSS subsystem. Each capture channel can be split into dual 8-bit SD channels, and display channels support simultaneous SD analog and HD digital (HDMI) output. This configuration is specified in Section 1.1 Features and Figure 1-1 of the SPRS614F datasheet.

What is the package type and pin count of the TMS320DM8167SCYG4?

The TMS320DM8167SCYG4 uses a 1031-pin FCBGA package with dimensions of 25.0 mm × 25.0 mm, manufactured using Via Channel technology to enable 0.8-mm PCB trace/space design rules. This package information is confirmed in the "Device Information" table on page 4 of the SPRS614F datasheet and Section 11.1 Packaging Information.
