Component qualification in accordance with JEDEC and industry standards to ensure reliable operation over an extended temperature range. This includes, but is not limited to, Highly Accelerated Stress Test (HAST) or biased 85/85, temperature cycle, autoclave or unbiased HAST, electromigration, bond intermetallic life, and mold compound life. Such qualification testing should not be viewed as justifying use of this component beyond specified performance and environmental limits.

The SM320LC31-EP digital signal processor (DSP) is a 32-bit, floating-point processor manufactured in 0.6-um triple-level-metal CMOS technology. The device is part of the SMJ320C3x generation of DSPs from Texas Instruments.
The SM320LC31-EP internal busing and special digital-signal-processing instruction set have the speed and flexibility to execute up to 60 MFLOPS. The SM320LC31-EP 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 SM320LC31-EP 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 SM320LC31-EP 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.
