description
The SMJ320C30 internal busing and special digital signal processor (DSP) instruction set has the speed and
flexibility to execute up to 50 MFLOPS. The SMJ320C30 device 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 emphasis on total system cost has resulted
in a less expensive processor that can be designed into systems currently using costly bit-slice processors.
