GENERAL DESCRIPTION
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 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.

Preliminary specification
SAA8122
Since one of the main objectives of the SAA8122E/C1 is addressing a wide range of CCD sensors, a DSP (with advanced
embedded algorithm) for camera signal processing is integrated with an high level of programmability for pulses
generation.
Another objective of the SAA8122E/C1 is to reach an high rate of picture compressed according to the JPEG standard.
So a JPEG codec block is also integrated in the chip
