LDK Solution
Introduction :
 

The LDK (Leopard Development Kit) is an ASIC version of the SOC development kit designed for the user to develop application and hardware/software easily. The LDK Development Board is an integrated system-on-chip development board with a built-in ARM926EJ processor core and Leopard Pro Core. It can be integrated with Customer's development boards through AHB extension, with up to 7 external bus masters and 8 external bus slaves. LDK can efficiently lower overall system cost, reduce development cycle time, and accelerate product introduction.

The board also provides I2C, SD, UART, RTC, SDR/DDR, 10/100 Ethernet, USB2.0 Device controller, PCI Host/Simple bridge, and MPGE4 encoder/decoder etc. circuit or peripherals as a reference design.

The LDK has a boot code in Flash for system initialization. User can then develop an application code via ICE and/or tool chain as well as various operating systems, BSP, drivers and reference applications.
