Chapter 1 <Introduction>

1.1 <Product Overview>

LP-150 is a Pico motherboard that based on Rockchip RK3128 high performance

Quad-core application processor to implement most useful features and functionalities of

this integrated processor. This motherboard is designed to be a development board for

customers to implement and verify their applications for RK3128 features.

The RK3128 Quad-core Cortex-A7 is integrates with separately Neon and FPU coprocessor,

also shared 256KB L2 Cache. Mali400 MP2 GPU is embedded to support smoothly

high-resolution (1080p) display and mainstream game.

Lots of high-performance interface to get very flexible solution, such as multi-pipe display

with HDMI1.4, TV Encoder. Crypto hardware is integrated for support security BOOT. 32bits

DDR3/LPDDR2 provides high memory bandwidths for high-performance.

The device enables OEMs and ODMs to quickly bring to market devices featuring robust

operating systems support, rich user interfaces, and high processing performance life

through the maximum flexibility of a fully integrated mixed processor solution.

The Cortex-A7 processor builds on the energy-efficient 8-stage pipeline of the Cortex-A5

processor. It also benefits from an integrated L2 cache designed for low-power, with lower

transaction latencies and improved OS support for cache maintenance. On top of this there

is improved branch prediction and an improved memory system performance, with 64-bit

load-store path, 128-bit AMBA4 AXI buses and increased TLB size (256 entry, up from 128

entry for Cortex-A9 and Cortex-A5), increasing performance for large workloads such as

web browsing.

In a 28nm process, the Cortex-A7 can run at 1.2-1.6GHz, has an area of 0.45mm2 (with

Floating-Point Unit, NEON and a 32KB L1 cache) and requires less than 100mW of total

power in typical conditions. This lowest performance profile makes it an ideal standalone

processor for a range of mobile devices, and means the Cortex-A7 can ultimately deliver

similar performance to the Cortex-A9 processor at much higher levels of power efficiency.
