description (continued)
The SMJ320C3x internal busing and special digital-signal-processing instruction set have the speed and
flexibility to execute up to 60 MFLOPS. The SMJ320C3x 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 SMJ320C3x 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.
High performance and ease of use are results of these features.
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 SMJ320C3x 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.
For additional information when designing for cold temperature operation, please see Texas Instruments
application report 320C3x, 320C4x and 320MCM42x Power-up Sensitivity at Cold Temperature, literature
number SGUA001.
