Texas Instruments TMS320VC5404

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 their memory maps. this section lists the p assignments and describes the function of each p . this data manual also provides a detailed description section electrical specifications parameter measurement formation and mechanical data about the available packag g. note: this data sheet is designed to be used conjunction with the tms320c5000 dsp family functional overview (literature number spru307). the 5407/5404 are based on an advanced modified harvard architecture that has one program memory bus and three data memory buses.

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. Separate program and data spaces allow simultaneous access to program instructions and data, providing a high degree of parallelism. Two read operations and one write operation can be performed in a single cycle. Instructions with parallel store and application-specific instructions can fully utilize this architecture. In addition, data can be transferred between data and program spaces. Such parallelism supports a powerful set of arithmetic, logic, and bit-manipulation operations that can all be performed in a single machine cycle. These DSPs also include the control mechanisms to manage interrupts, repeated operations, and function calls.
