描述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.
