DSP-Memory
- 104K x 16bit Program ROM
- 8k x 16bit Program RAM
- 60k x 16bit Data ROM
- 37k x 16bit Data RAM
- Incremental Redundancy(IR) Memory of 35904 words of 16bit
Shared Memory Block
1.5K x 32bit Shared RAM(dual ported) between controller system and TEAKLite.
Controller Bus system
The processor cores and their peripherals are connected by powerful buses.
Multi-layer AHB for connecting the ARM and the other master capable building blocks with the internal
and external memories and with the peripheral buses.
Clock system
The clock system allows widely independent selection of frequencies for the essential parts of the
S-GOLD3. Thus power consumption and performance can be optimized for each application.
Functional Hardware block
