产品概述
The TMS320VC5501 (5501) fixed-point digital signal processor (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 reduction in power dissipation. The CPU supports an internal bus structure that is composed of one program bus, three data read buses, two data
write buses, and additional buses dedicated to peripheral and DMA activity. These buses provide the ability to perform up to three data reads and two data
writes in a single cycle. In parallel, the DMA controller can perform data
transfers independent of the CPU activity.The C55x™ CPU provides two multiply-accumulate (MAC) units, each capable of 17-bit × 17-bit multiplication 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 DSP generation 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 AU and DU
resources, and manages the fully protected pipeline. Predictive branching
capability avoids pipeline flushes on execution of conditional instructions.
The 5501 peripheral set includes an external memory interface (EMIF) that
provides glueless access to asynchronous memories like EPROM and SRAM, as well
as to high-speed, high-density memories such as synchronous DRAM and synchronous
burst RAM. Additional peripherals include UART, watchdog timer, and an I-Cache.
Two full-duplex multichannel buffered serial ports (McBSPs) provide glueless
interface to a variety of industry-standard serial devices, and multichannel
communication with up to 128 separately enabled channels. The host-port
interface (HPI) is an 8-bit parallel interface used to provide host processor
access to 16K words of internal memory on the 5501. The HPI operates in
multiplexed mode to provide glueless interface to a wide variety of host
processors. The DMA controller provides data movement for six independent
channel contexts without CPU intervention. Two general-purpose timers, eight
dedicated general-purpose I/O (GPIO) pins, and analog phase-locked loop (APLL)
clock generation are also included.The 5501 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. The Code Composer Studio× IDE features code generation tools that include a C Compiler, Visual Linker, simulator, RTDX™, XDS510™ emulation device drivers, and evaluation modules. The 5501 is also supported by the C55x™ DSP Library, which features more than 50 foundational software kernels (FIR filters, IIR filters, FFTs, and various math functions) as well as chip and board support libraries.
