Introduction

The D950-Core is a general purpose programmable 16-bit fixed point Digital Signal Processor Core, designed for multimedia, telecom and datacom applications. The D950-Core is a core product, used in combination with standard or custom peripherals from the standard cell library. The peripherals are implemented around the core on the same silicon die, for application specific DSP silicon chip design.

The main blocks of the D950-Core include an arithmetic data calculation unit, a program control unit and an address calculation unit, able to manage up to 64k (program) and 128k (data) x 16-bit memory spaces. Standard peripherals from the macrocell library include an Emulation Unit, a Bus Switch Unit, an Interrupt Controller, a DMA Controller, a Timer and a Synchronous Serial Port. Memory can be added for programs or data and dedicated memory cells can be generated by use of RAM and ROM memory generators. The development of application specific peripherals is simplified by using the standard cells library.
