TMS320C6745 ， TMS320C6747固定/浮点数字信号处理器 TMS320C6745,TMS320C6747 Fixed/Floating-Point Digital Signal Processor

The TMS320C6745/6747 device is a low-power digital signal processor based on a TMS320C674x DSP core. It consumes significantly lower power than other members of the TMS320C6000 platform of DSPs.

The TMS320C6745/6747 device enables original-equipment manufacturers OEMs and original-design manufacturers ODMs to quickly bring to market devices featuring high processing performance .

The TMS320C6745/6747 DSP core uses a two-level cache-based architecture. The Level 1 program cache L1P is a 32-KB direct mapped cache and the Level 1 data cache L1D is a 32-KB 2-way set-associative cache. The Level 2 program cache L2P consists of a 256-KB memory space that is shared between program and data space. L2 memory can be configured as mapped memory, cache, or combinations of the two. Although the DSP L2 is accessible by other hosts in the system, an additional 128KB of RAM shared memory TMS320C6747 only is available for use by other hosts without affecting DSP performance.

The peripheral set includes: a 10/100 Mbps Ethernet MAC EMAC with a management data input/output MDIO module; two I2C Bus interfaces; 3 multichannel audio serial ports McASPs with 16/9 serializers and FIFO buffers; two 64-bit general-purpose timers each configurable one configurable as watchdog; a configurable 16-bit host-port interface HPI [TMS320C6747 only]; up to 8 banks of 16 pins of general-purpose input/output GPIO with programmable interrupt/event generation modes, multiplexed with other peripherals; 3 UART interfaces one with both RTS and CTS; three enhanced high-resolution pulse width modulator eHRPWM peripherals; three 32-bit enhanced capture eCAP module peripherals which can be configured as 3 capture inputs or 3 auxiliary pulse width modulator APWM outputs; two 32-bit enhanced quadrature encoded pulse eQEP peripherals; and 2 external memory interfaces: an asynchronous and SDRAM external memory interface EMIFA for slower memories or peripherals, and a higher speed memory interface EMIFB for SDRAM.

The Ethernet Media Access Controller EMAC provides an efficient interface between the TMS320C6745/6747 device and the network. The EMAC supports both 10Base-T and 100Base-TX, or 10 Mbps and 100 Mbps in either half- or full-duplex mode. Additionally, an MDIO interface is available for PHY configuration.

The rich peripheral set provides the ability to control external peripheral devices and communicate with external processors. For details on each of the peripherals, see the related sections later in this document and the associated peripheral reference guides.
