Vortex86DX2
32-Bit X86 MicroProcessor
Overview
The Vortex86DX2 is a high performance and fully static
FIFO UART, USB2.0 Host and IDE/SATA controller within a
32-bit X86 processor with the compatibility of Windows based,
single 720-pin BGA package to form a system-on-a-chip
Linux and most popular 32-bit RTOS. It also integrates 32KB
(SOC). It provides an ideal solution for the embedded system
write through 4-way L1 cache, 256KB write through/write
and communications products (such as thin client, NAT router,
back 4-way L2 cache, PCIE bus in at 2.5 GHz, DDR2, ROM
home gateway, access point and tablet PC) to bring about
controller, ISA, I2C, SPI, IPC (Internal Peripheral Controllers
desired performance.
with DMA and interrupt timer/counter included), Fast Ethernet,
