The TMS320C64x DSPs (including the TMS320C6413, TMS320C6410 devices) are the highest-performance fixed-point DSP generation in the TMS320C6000 DSP platform. The TMS320C6413 and TMS320C6410 (C6413 and C6410) devices are based on the second-generation high-performance, advanced VelociTI very-long-instruction-word (VLIW) architecture (VelociTI.2) developed by Texas Instruments (TI) The high-performance, lower-cost C6413/C6410 DSPs enable customers to reduce system costs for telecom, medical, industrial, office, and photo lab equipment. The C64x is a code-compatible member of the C6000 DSP platform.
With performance of up to 4000 million instructions per second (MIPS) at a clock rate of 500 MHz, the C6413 device offers cost-effective solutions to high-performance DSP programming challenges.
With performance of up to 3200 million instructions per second (MIPS) at a clock rate of 400 MHz, the C6410 device offers cost-effective solutions to high-performance DSP programming challenges. The C6410 device also provides excellent value for packet telephony and for other cost-sensitive applications demanding high performance.

The C6413/C6410 DSP possesses the operational flexibility of high-speed controllers and the numerical capability of array processors. The C64x DSP core processor has 64 general-purpose registers of 32-bit word length and eight highly independent functional unitstwo multipliers for a 32-bit result and six arithmetic logic units (ALUs) with VelociTI.2 extensions. The VelociTI.2 extensions in the eight functional units include new instructions to accelerate the performance in video and imaging applications and extend the parallelism of the VelociTI architecture. The C6413 can produce four 16-bit multiply-accumulates (MACs) per cycle for a total of 2000 million MACs per second (MMACS), or eight 8-bit MACs per cycle for a total of 4000 MMACS. The C6410 can produce four 16-bit multiply-accumulates (MACs) per cycle for a total of 1600 million MACs per second (MMACS), or eight 8-bit MACs per cycle for a total of 3200 MMACS. The C6413/C6410 DSP also has application-specific hardware logic, on-chip memory, and additional on-chip peripherals similar to the other C6000 DSP platform devices.
The C6413/C6410 uses a two-level cache-based architecture and has a powerful and diverse set of peripherals. The Level 1 program cache (L1P) is a 128-Kbit direct mapped cache and the Level 1 data cache (L1D) is a 128-Kbit 2-way set-associative cache. The Level 2 memory/cache (L2) consists of an 2-Mbit memory space that is shared between program and data space [for C6413 device] and the Level 2 memory/cache (L2) consists of an 1-Mbit memory space that is shared between program and data space [for C6410 device]. L2 memory can be configured as mapped memory, cache, or combinations of the two. The peripheral set includes: two multichannel buffered audio serial ports (McASPs); two inter-integrated circuit bus modules (I2Cs) ; two multichannel buffered serial ports (McBSPs); three 32-bit general-purpose timers; a user-configurable 16-bit or 32-bit host-port interface (HPI16/HPI32); a 16-pin general-purpose input/output port (GP0) with programmable interrupt/event generation modes; and a 32-bit glueless external memory interface (EMIFA), which is capable of interfacing to synchronous and asynchronous memories and peripherals.
The McASP port supports one transmit and one receive clock zone, with eight serial data pins which 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 C6413/C6410 has sufficient bandwidth to support all 8 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, CP-430 encoded data channels simultaneously, with a single RAM containing the full implementation of user data and channel status fields.
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 I2C ports on the TMS320C6413/C6410 allows 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.
TheC6413/C6410 has a complete set of development tools which includes: a new C compiler, an assembly optimizer to simplify programming and scheduling, and a Windows debugger interface for visibility into source code execution.
