description
The TMP/SMJ320C31KGD digital signal processor (DSP) is a high-performance, 32-bit floating-point
processor manufactured in 0.72-
μ
m, double-level metal CMOS technology.
The TMP/SMJ320C31KGD’s internal busing and special digital signal processing instruction set have the speed
and flexibility to execute up to 40 million floating-point operations per second (MFLOPS). The
TMP/SMJ320C31KGD 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 TMP/SMJ320C31KGD 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.
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of
Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
PRODUCTION DATA information is current as of publication date.
Products conform to specifications per the terms of Texas Instruments
standard warranty. Production processing does not necessarily include
testing of all parameters.
