Introduction
The ST18952 chip includes the SGS-Thomson D950 16-bit fixed point digital signal processor
core, 16.5 Kwords of data memory, 32 Kwords of program memory, and the following on-chip
peripherals:
• Interrupt controller (ITC)
• DMA controller (DMA)
• Bus switch unit (BSU)
• Synchronous input/output (SIO)
• Timer (TIM)
• Emulation unit (EMU)
• Tap controller (TAP)
It also includes an oscillator and a PLL for generation of the D950Core clock.
The ST18952 is used on the D950 Emulation Card (called the D952 module) developed by
SGS-Thomson.
It can also be used for application development by customers.
Custom development is eased by providing direct access to the D950 instruction and data
buses to allow simultaneous access to external memories or peripherals (with wait-states).
For full details of the D950Core refer to the D950Core datasheet (
document number 42-1709).
