2 Description
The SMx320VC33 DSP is a 32-bit, floating-point
processor manufactured in 0.18-μm four-level-metal
CMOS (TImeline) technology. The SMx320VC33 is
part of the SM320C3x™ generation of DSPs from
Texas Instruments.
The SM320C3x internal busing and special digital-
signal-processing instruction set have the speed and
flexibility to execute up to 150 MFLOPS. The
SMx320VC33 optimizes speed by implementing
functions in hardware that other processors
implement through software or microcode. This
hardware-intensive approach provides performance
previously unavailable on a single chip.
The SMx320VC33 can perform parallel multiply and
ALU operations on integer or floating-point data in a
single cycle. Each processor also possesses a
general-purpose register file, a program cache,
dedicated ARAUs, internal dual-access memories,
one DMA channel supporting concurrent I/O, and a
short machine-cycle time. These features result in
high performance and ease of use. General-purpose
applications are greatly enhanced by the large
address space, multiprocessor interface, internally
and externally generated wait states, one external
interface port, two timers, one serial port, and
multiple-interrupt structure.
The SM320C3x supports a wide variety of system
applications from host processor to dedicated
coprocessor. High-level-language support is easily
implemented through a register-based architecture,
large address space, powerful addressing modes,
flexible instruction set, and well-supported floating-
point arithmetic.
