These processors also provide an arithmetic logic unit (ALU) that has a high degree of parallelism, application-specific hardware logic, on-chip memory, and additional on-chip peripherals. These DSP families also provide a highly specialized instruction set, which is the basis of the operational flexibility and speed of these DSPs. Separate program and data spaces allow simultaneous access to program instructions and data, providing the high degree of parallelism. Two reads 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. In addition, the ’C54x, ’LC54x, and ’VC54x versions include the control mechanisms to manage interrupts, repeated operations, and function calls. Table 1 provides an overview of the ’54x generation of DSPs. The table shows significant features of each device including the capacity of on-chip RAM and ROM memories, the peripherals, the execution time of one machine cycle, and the type of package with its total pin count.
