The SMJ320C30KGDB digital signal processor (DSP) is a high-performance, 32-bit floating-point processor manufactured in 0.72-µm, double-level metal CMOS technology.
●The SMJ320C30KGDB internal busing and special digital-signal-processing instruction set have the speed and flexibility to execute up to 50 million floating-point operations per second (MFLOPS). The SMJ320C30KGDB 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 SMJ320C30KGDB 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, two external interface ports, two timers, two serial ports, and multiple interrupt structure enhanced general-purpose applications. The SMJ320C30KGDB 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.
