SAA8122

The DSC SAA8122E/C1 is a high performance, low power, single-chip MIPS based microprocessor which is dedicated to image processing and compression.

The DSC SAA8122E/C1 is a highly complex integrated microprocessor system, consisting of one 32-bits RISC CPU (PR3001), a BCU, an interrupt controller and a power management controller, a ROM/DRAM/SRAM/FLASH/PC-card memory controller, a JPEG encoder/decoder, a Progammable Pulse Generator, a specific DSP for image processing, an SDRAM memory controller, a number of standard peripheral modules (like IO ports, timers, a real-time clock, UART, USB, FIR, and an I2C transceiver) and a Test Control Block module. The  DSC SAA8122E/C1 is based on the PRISC (Philips RISC) architecture framework.

The objective of the DSC SAA8122E/C1 is twofold. In the first place, the SAA8122E/C1 is design to propose to the customer a one chip able to perform all treatments and connections required for a wide range of Digital Still Camera. In the second place, the SAA8122E/C1 is design around a RISC CPU for which the development environment is already available and validate to speed up the software development time.
