TEXAS INSTRUMENTS AM1808BZWTD4 芯片, 微处理器, 32位, 456MHZ, NFBGA-361
The Sitara - AM1x series ARM Microprocessor enables original-equipment manufacturers OEMs and original-design manufacturers 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 ARM926EJ-S is a 32-bit RISC processor core that performs 32-bit or 16-bit instructions and processes 32-, 16- or 8-bit data. The core uses pipelining so that all parts of the processor and memory system can operate continuously. The ARM core has a coprocessor 15 CP15, protection module and data and program memory management units MMUs with table look-aside buffers. The ARM core processor has separate 16kB instruction and 16kB data caches. Both are four-way associative with virtual index virtual tag VIVT. The ARM core also has 8kB of RAM Vector Table and 64kB of ROM.
