The TMS320C67x DSPs (including the SM320C6713 and SM320C6713B devices) compose the floating-point DSP generation in the TMS320C6000 DSP platform. The C6713 and C6713B devices are based on the high-performance, advanced very-long-instruction-word (VLIW) architecture developed by Texas Instruments (TI), making this DSP an excellent choice for multichannel and multifunction applications. Throughout the remainder of this document, the SM320C6713 and SM320C6713B are referred to as 320C67x or C67x or 13/13B where generic, and where specific, their individual full device part numbers are used or abbreviated as C6713, C6713B, 13, or 13B, and so forth.
Operating at 225 MHz, the C6713/13B delivers up to 1350 million floating-point operations per second (MFLOPS), 1800 million instructions per second (MIPS), and with dual fixed-/floating-point multipliers up to 450 million multiply-accumulate operations per second (MMACS).
Operating at 300 MHz, the C6713B delivers up to 1800 million floating-point operations per second (MFLOPS), 2400 million instructions per second (MIPS), and with dual fixed-/floating-point multipliers up to 600 million multiply-accumulate operations per second (MMACS).
The C6713/13B has a rich peripheral set that includes two multichannel audio serial ports (McASPs), two multichannel buffered serial ports (McBSPs), two inter-integrated circuit (I2C) buses, one dedicated general-purpose input/output (GPIO) module, two general-purpose timers, a host-port interface (HPI), and a glueless external memory interface (EMIF) capable of interfacing to SDRAM, SBSRAM, and asynchronous peripherals.
The two McASP interface modules each support one transmit and one receive clock zone. Each of the McASPs has eight serial data pins that can be individually allocated to any of the two zones. The serial port supports time-division multiplexing on each pin from 2 to 32 time slots. The C6713/13B has sufficient bandwidth to support all 16 serial data pins transmitting a 192-kHz stereo signal. Serial data in each zone may be transmitted and received on multiple serial data pins simultaneously and formatted in a multitude of variations on the Philips Inter-IC Sound (I2S) format.
In addition, the McASP transmitter may be programmed to output multiple S/PDIF, IEC60958, AES-3, and CP-430 encoded data channels simultaneously, with a single RAM containing the full implementation of user data and channel status fields.
The McASP also provides extensive error-checking and recovery features, such as the bad clock detection circuit for each high-frequency master clock, which verifies that the master clock is within a programmed frequency range.
The two I2C ports on the 320C6713/13B allow the DSP to easily control peripheral devices and communicate with a host processor. In addition, the standard multichannel buffered serial port (McBSP) may be used to communicate with serial peripheral interface (SPI™) mode peripheral devices.
The 320C6713/13B device has two boot modes—from the HPI or from external asynchronous ROM. For more detailed information, see the Bootmode section of this data sheet.
The TMS320C67x DSP generation is supported by the TI eXpressDSP set of industry benchmark development tools, including a highly optimizing C/C++ Compiler, the Code Composer Studio Integrated Development Environment (IDE), JTAG-based emulation and real-time debugging, and the DSP/BIOS kernel.
