3 AT91SC192192CT-USB 6556a?spic?16 may 07 architectural overview the sc100 is a 3 stage pipeline, 32-bit risc processor. it us es a von neumann load/store arch itecture, this architecture is characterized by a single data and address bus for instruction data. the sc100 processor employs a unique architectural strat egy known as thumb ? , a super reduced instruction set that is ideally suited for hi gh volume applications with memory restrictions, and app lications where code density is an importan t factor. essentially, the sc100 processor has two instruction sets: ? the standard arm instruction set using 32-bit instructions and offering maximum performance ? the thumb instruction set usin g 16-bit instructions and of fering maximum code density both instruction sets operate on 8-bit, 16-bit and 32-bit data types. the thumb?s 16-bit instruction length allows it to achieve almost twice the density of standard arm code, whilst retaining most of the arm performance advantage over a traditional 16-bi t processor using 16-bit registers. this is possible because the 16-bit thumb instructions operate on the same 32-bit regi ster set as the 32-bit arm instruction set. thumb code can be up to 35% smaller than the equivalent arm code, whilst providing 160% of the performance of an equivalent arm processor connected to a 16-bit memory system. usb xin usb xin io3 flash interface io3 usb xout usb xout ss /io4 spi slave select/flash interface io4 wp flash interface (write protect) sck/io5 spi clock/flash interface io5 mosi/io6 spi master output-slave input/flash interface io6 miso/io7 spi master output-slave input/flash interface io7
