architectural overview
The functional block diagram provides a high-level description of each component in the ’F243/’F241 DSP
controllers. The TMS320x24x devices are composed of three main functional units: a ’C2xx DSP core, internal
memory, and peripherals. In addition to these three functional units, there are several system-level features of
the ’F243/’F241 that are distributed. These system features include the memory map, device reset, interrupts,
digital input/output (I/O), clock generation, and low-power operation.
system-level functions
device memory maps
The ’F243/’F241 devices implement three separate address spaces for program memory, data memory, and
I/O space. On the ’F243/’F241, the first 96 (0–5Fh) data memory locations are either allocated for
memory-mapped registers or reserved. This memory-mapped register space contains various control and
status registers, including those for the CPU.
All the on-chip peripherals of the ’F243/’F241 devices are mapped into data memory space. Access to these
registers is made by the CPU instructions addressing their data memory locations. Figure 1 shows the ’F243
memory map and Figure 2 shows the ’F241 memory map.
