The i.MX35 core is intended to operate at a maximum frequency of 532 MHz to support the required
multimedia use cases. Furthermore, an image processing unit (IPU) is integrated into the AP domain to
offload the ARM11 core from performing functions such as color space conversion, image rotation and
scaling, graphics overlay, and pre- and post-processing.
The functionality of AP Domain peripherals includes the user interface; the connectivity, display, security,
and memory interfaces; and 128 Kbytes of multipurpose SRAM.
2.2
The shared domain is composed of the shared peripherals, a smart DMA engine (SDMA) and a number of
miscellaneous modules. For maximum flexibility, some peripherals are directly accessible by the SDMA
engine.
The i.MX35 has a hierarchical memory architecture including L1 caches and a unified L2 cache. This
reduces the bandwidth demands for the external bus and external memory. The external memory
subsystem supports a flexible external memory system, including support for SDRAM (SDR, DDR2 and
mobile DDR) and NAND Flash.
2.3
To address the continuing need to reduce power consumption, the following techniques are incorporated
in the i.MX35:
The insertion of gating into the clock paths allows unused portions of the chip to be disabled. Because
static CMOS logic consumes only leakage power, significant power savings can be realized.
“Well biasing” is applying a voltage that is greater than V
to the pwells. The effect of applying this well back bias voltage reduces the subthreshold channel leakage.
For the 90-nm digital process, it is estimated that the subthreshold leakage is reduced by a factor of ten
over the nominal leakage. Additionally, the supply voltage for internal logic can be reduced from 1.4 V to
1.22 V.
2.4
The CPU of the i.MX35 is the ARM1136JF-S core, based on the ARM v6 architecture. This core supports
the ARM Thumb
byte codes) and a range of SIMD DSP instructions that operate on 16-bit or 8-bit data values in 32-bit
registers.
