Fixed-Point Digital Signal Processor
SPRS139G–NOVEMBER 2000–REVISED JANUARY 2005
The following functional overview is based on the block diagram in Figure 3-1.
Figure 3-1. TMS320VC5410A Functional Block Diagram
The 5410A device provides both on-chip ROM and RAM memories to aid in system performance and
integration.
The data memory space addresses up to 64K of 16-bit words. The device automatically accesses the
on-chip RAM when addressing within its bounds. When an address is generated outside the RAM bounds,
the device automatically generates an external access.
The advantages of operating from on-chip memory are as follows:
Higher performance because no wait states are required
Higher performance because of better flow within the pipeline of the central arithmetic logic unit
(CALU)
Lower cost than external memory
Lower power than external memory
The advantage of operating from off-chip memory is the ability to access a larger address space.
