The TMS320VC5402A fixed-point, digital signal processor (DSP) (hereafterreferred to as the 5402A unless otherwise specified) is based on an advancedmodified Harvard architecture that has one program memory bus and three datamemory buses. This processor provides an arithmetic logic unit (ALU) with a highdegree of parallelism, application-specific hardware logic, on-chip memory, andadditional on-chip peripherals. The basis of the operational flexibility andspeed of this DSP is a highly specialized instruction set.\n Separate program and data spaces allow simultaneous access to programinstructions and data, providing a high degree of parallelism. Two readoperations and one write operation can be performed in a single cycle.Instructions with parallel store and application-specific instructions can fullyutilize this architecture. In addition, data can be transferred between data andprogram spaces. Such parallelism supports a powerful set of arithmetic, logic,and bit-manipulation operations that can all be performed in a single machinecycle. The 5402A also includes the control mechanisms to manage interrupts,\n
