description

The TMP/SMJ320C31KGDB and SMJ320LC31KGDB digital signal processors (DSPs) known good dies (KGDs) are high-performance, 32-bit floating-point processors manufactured in 0.72-um, double-level metal CMOS technology.

The TMP/SMJ320C31KGDB and SMJ320LC31KGDB 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 devices optimize 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 devices 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.

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 enhance general-purpose applications. The TMP320C31KGDB and the SMJ320C31KGDB support a wide variety of system applications from host processor to dedicated coprocessor.

High-level language support is implemented through a register-based architecture, large address space, and the device's ability to execute 40 million floating-point operations per second (MFLOPS) and perform parallel multiple and ALU operations.
