Fixed-Point Digital Signal Processor

The TMS320C64x+ DSPs (including the TMS320C6454 device) are the highest-performance fixed-point DSP generation in the TMS320C6000 DSP platform. The C6454 device is based on the third-generation high-performance, advanced VelociTI very-long-instruction-word (VLIW) architecture dev c0c eloped by Texas Instruments (TI), making these DSPs an excellent choice for applications including Video and telecom infrastructure, imaging/medical, and Wireless infrastructure (WI). The C64x+ devices are upward code-compatible from previous devices that are part of the C6000 DSP platform.
The C6454 offers a lower cost pin-compatible migration path for C6455 customers who don't need the 2MB of the C6455 or the high-speed interconnect provided by Serial RapidIO. The C6454 also provides an excellent migration path for existing C6414/6415/6416 customers who require C6454 advanced peripherals; DDR2 at 533 MHz provides 2x performance boost over older SDRAM Interface gigabit Ethernet provides low-cost high-performance ubiquitous packet Interface and 66-MHz PCI (revision 2.3 complaint) provides legacy high-bandwidth interconnect.
Based on 90-nm process technology and with performance of up to 8000 million instructions per second (MIPS) [or 8000 16-bit MMACs per cycle] at a 1-GHz Clock rate, the C6454 device offers cost-effective solutions to high-performance DSP programming challenges. The C6454 DSP possesses the operational flexibility of high-speed controllers and the numerical capability of array processors.
The C64x+ DSP core employs eight functional units, two Register files, and two data paths. Like the earlier C6000 devices, two of these eight functional units are multipliers or .M units. Each C64x+ .M unit doubles the multiply throughput versus the C64x core by performing four 16-bit x 16-bit multiply-accumulates (MACs) every Clock cycle. Thus, eight 16-bit x 16-bit MACs CAN be executed every cycle on the C64x+ core. At a 1-GHz Clock rate, this means 8000 16-bit MMACs CAN occur every second. Moreover, each multiplier on the C64x+ core CAN compute one 32-bit x 32-bit MAC or four 8-bit x 8-bit MACs every Clock cycle.
The C6454 DSP integrates a large amount of on-chip memory organized as a two-level memory system. The level-1 (L1) program and data Memories on the C6454 device are 32KB each. This memory CAN be configured as mapped RAM, cache, or some combination of the two. When configured as cache, L1 program (L1P) is a direct mapped cache where as L1 data (L1D) is a two-way set associative cache. The level 2 (L2) memory is shared between program and data space and is 1048KB in size. L2 memory CAN also be configured as mapped RAM, cache, or some combination of the two. The C64x+ Megamodule also has a 32-bit peripheral configuration (CFG) port, an internal DMA (IDMA) controller, a system component with reset/boot control, interrupt/exception control, a power-down control, and a free-running 32-bit Timer for time stamp.
The peripheral set includes: an inter-integrated circuit bus module (I2C); two multichannel buffered serial ports (McBSPs); a user-configurable 16-bit or 32-bit host-port Interface (HPI16/HPI32); a peripheral component interconnect (PCI); a 16-pin general-purpose input/output port (GPIO) with programmable interrupt/event generation modes; an 10/100/1000 Ethernet b54 media access controller (EMAC), which provides an efficient Interface between the C6454 DSP core processor and the network; a management data input/output (MDIO) module (also part of the EMAC) that continuously polls all 32 MDIO addresses in order to enumerate all PHY devices in the system; a glueless external memory Interface (64-bit EMIFA), which is capable of interfacing to synchronous and asynchronous peripherals; and a 32-bit DDR2 SDRAM Interface
The I2C ports on the C6454 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.
The C6454 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.
