TMS320DM8127BCYE2 Overview

TMS320DM8127 DaVinci Digital Media processors are highly integrated,programmable platforms that leverage the technology to meet the processing needsof the following applications to name a few:IP Network Cameras IndustrialAutomation Network Cameras Stereo Cameras Video Surveillance HD VideoConferencing Car Black BoxHome Audio and Video Equipment

The device enables Original-Equipment Manufacturers (OEMs) andOriginal-Design Manufacturers (ODMs) to quickly bring to market devicesfeaturing robust operating systems support, rich user interfaces, and highprocessing performance through the maximum flexibility of a fully integratedmixed processor solution. The device also combines programmable video and audioprocessing with a highly integrated peripheral set.

Programmability is provided by an ARM Cortex-A8 RISC CPU with Neon extension,TI C674x VLIW floating-point DSP core, and high-definition video and imagingcoprocessors. The ARM lets developers keep control functions separate from A/Valgorithms programmed on the DSP and coprocessors, thus reducing the complexityof the system software. The ARM Cortex-A8 32-Bit RISC Core with Neonfloating-point extension includes: 32KB of Instruction cache; 32KB of Datacache; 256KB of L2 Cache; 48KB of Boot ROM; and 64KB of RAM.

The rich peripheral set provides the ability to control external peripheraldevices and communicate with external processors. For details on each of theperipherals, see the related sections in this document and the associatedperipheral reference guides. The peripheral set includes: HD Video ProcessingSubsystem Dual Port Gigabit Ethernet MACs (10/100/1000 Mbps) [Ethernet Switch]with MII/RMII/GMII/RGMII and MDIO interface supporting IEEE 1588 Time-Stamping,AVB, and Industrial Ethernet ProtocolsTwo USB ports with integrated 2.0 PHY PCIex1 GEN2 Compliant interfaceTwo 10-serializer McASP audio serial ports (with DITmode)Four quad-serilaizer McASP audio serial ports (with DIT mode)One McBSPmultichannel buffered serial portSix UARTs with IrDA and CIR supportFour SPIserial interfacesThree MMC/SD/SDIO serial interfacesFour I2C masterand slave interfaces Parallel Camera Interface (CAM)Up to128 General-Purpose I/Os (GPIOs)Eight 32-bit general-purpose timers Systemwatchdog timer Dual DDR2, and DDR3 SDRAM interfacesFlexible 8- or 16-bitasynchronous memory interfaceTwo Controller Area Network (DCAN) modulesSpinLockMailbox

The TMS320DM8127 DaVinci Digital Media processors also include ahigh-definition video and imaging coprocessor 2 (HDVICP2) to off-load many videoand imaging processing tasks from the DSP core, making more DSP MIPS availablefor common video and imaging algorithms. Additionally, the TMS320DM8127 DaVinciDigital Media processors have a complete set of development tools for both theARM and DSP which include C compilers, a DSP assembly optimizer to simplifyprogramming and scheduling, and a Microsoft? Windows? debugger interface forvisibility into source code execution.

The C674x DSP core is the high-performance floating-point DSP generation inthe TMS320C6000 DSP platform and is code-compatible with previous generationC64x Fixed-Point and C67x Floating-Point DSP generation. The C674xFloating-Point DSP processor uses 32KB of L1 program memory with EDC and 32KB ofL1 data memory. Up to 32KB of L1P can be configured as program cache. Theremaining memory is noncacheable no-wait-state program memory. Up to 32KB of L1Dcan be configured as data cache. The remaining memory is noncacheableno-wait-state data memory. The DSP has 256KB of L2 RAM with ECC, which can bedefined as SRAM, L2 cache, or a combination of both. All C674x L3 and off-chip
