description
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 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.
