1.3 Description

The device is a member of TI's TMS320C5000™ fixed-point Digital Signal Processor (DSP) product family

and is designed for low-power applications.

The fixed-point DSP is based on the TMS320C55x™ DSP generation CPU processor core. The C55x™

DSP architecture achieves high performance and low power through increased parallelism and total focus

on power savings. The CPU supports an internal bus structure that is composed of one program bus, one

32-bit data read bus and two 16-bit data read buses, two 16-bit data write buses, and additional buses

dedicated to peripheral and DMA activity. These buses provide the ability to perform up to four 16-bit data

reads and two 16-bit data writes in a single cycle. The device also includes four DMA controllers, each

with 4 channels, providing data movement for 16-independent channel contexts without CPU intervention.

Each DMA controller can perform one 32-bit data transfer per cycle, in parallel and independent of the

CPU activity.

The C55x CPU provides two multiply-accumulate (MAC) units, each capable of 17-bit x 17-bit

multiplication and a 32-bit add in a single cycle. A central 40-bit arithmetic/logic unit (ALU) is supported by

an additional 16-bit ALU. Use of the ALUs is under instruction set control, providing the ability to optimize

parallel activity and power consumption. These resources are managed in the Address Unit (AU) and Data

Unit (DU) of the C55x CPU.

The C55x CPU supports a variable byte width instruction set for improved code density. The Instruction

Unit (IU) performs 32-bit program fetches from internal or external memory and queues instructions for the

Program Unit (PU). The Program Unit decodes the instructions, directs tasks to the Address Unit (AU) and

Data Unit (DU) resources, and manages the fully protected pipeline. Predictive branching capability avoids

pipeline flushes on execution of conditional instructions.

Serial media is supported through two MultiMedia Card/Secure Digital (MMC/SD) peripherals, four Inter-IC

Sound (I2S Bus™) modules, one Serial-Port Interface (SPI) with up to 4 chip selects, one I2C multimaster

and slave interface, and a Universal Asynchronous Receiver/Transmitter (UART) interface.

The device peripheral set includes an external memory interface (EMIF) that provides glueless access to

asynchronous memories like EPROM, NOR, NAND, and SRAM, as well as to high-speed, high-density

memories such as synchronous DRAM (SDRAM) and mobile SDRAM (mSDRAM). Additional peripherals

include: a high-speed Universal Serial Bus (USB2.0) device mode only, and a real-time clock (RTC). This

device also includes three general-purpose timers with one configurable as a watchdog timer, and an

analog phase-locked loop (APLL) clock generator.

The device includes one integrated LDO (ANA_LDO) to provide regulated 1.3 V to the DSP PLL

(VDDA_PLL). Note: ANA_LDO can only provide a regulated 1.3 V. When the DSP PLL requires 1.4 V

(PLLOUT > 120 MHz), an external supply is required to supply 1.4 V to the DSP PLL (VDDA_PLL).

The device is supported by the industry’s award-winning eXpressDSP™, Code Composer Studio™

Integrated Development Environment (IDE), DSP/BIOS™, Texas Instruments’ algorithm standard, and the

industry’s largest third-party network. Code Composer Studio IDE features code generation tools including

a C Compiler and Linker, RTDX™, XDS100™, XDS510™, XDS560™ emulation device drivers, and

evaluation modules. The device is also supported by the C55x DSP Library which features more than 50

foundational software kernels (FIR filters, IIR filters, and various math functions) as well as chip support

libraries.
