Introduction
●This data manual discusses features and specifications of the TMS320VC5407 and TMS320VC5404 (hereafter referred to as the 5407/5404 unless otherwise specified) digital signal processors (DSPs). The 5407 and 5404 are essentially the same device except for differences in their memory maps.
●This section lists the pin assignments and describes the function of each pin. This data manual also provides a detailed description section, electrical specifications, parameter measurement information, and mechanical data about the available packaging.
●Description
●The 5407/5404 are based on an advanced modified Harvard architecture that has one program memory bus and three data memory buses. These processors provide an arithmetic logic unit (ALU) with a high degree of parallelism, application-specific hardware logic, on-chip memory, and additional on-chip peripherals. The basis of the operational flexibility and speed of these DSPs is a highly specialized instruction set.
