description
The SMJ320C30 internal busing and special digital signal processor (DSP) instruction set has the speed and
flexibility to execute up to 50 MFLOPS. The SMJ320C30 device 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 emphasis on total system cost has resulted
in a less expensive processor that can be designed into systems currently using costly bit-slice processors.

The SMJ320C30 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 enhanced by the large address space, multiprocessor interface, internally
and externally generated wait states, two external interface ports, two timers, two serial ports, and multiple
interrupt structure. The SMJ320C30 supports a wide variety of system applications from host processor to
dedicated coprocessor.
High-level language support is implemented easily 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.
