TMS320LC546A Floating-Point Digital Signal Processor

The TMS320C54x, TMS320LC54x, and TMS320VC54x fixed-point, digital signal processor (DSP) families (hereafter referred to as the ’54x unless otherwise specified) are based on an advanced modified Harvard architecture that has one program memory bus and three data memory buses. These processors also provide an arithmetic logic unit (ALU) that has a high degree.
