bo bo wai maung gives a topic for sig-hardware

Sep 26

while thinking abt what to write out for a topic, some thoughts of what i encounterd this breakfast time are coming up in procedual trails: FPGA based PCI express for 64bit processing environment, Intel's IXP processor for network processing, information integrated power management for wireless sensor network and crush-free RTOS framework. But finally made up my mind to figure out some of the fundamental concepts and product knowledge of this week hot controller Microchip PIC18F97J60.it is just a MIPS based 8bit MCUs but optimized for remote communication based embedded solution. it means it has IEEE 802.3 compliant Ethernet based on-chip PHY and MAC controller.well let's stop here abt product.
do u understand what i described before?

MCU - it is microcontroller unit which integrate microprocessor, RAM, ROM (for firmware) and other IO module into a single chip. so we sometimes call (system on chip)

MIPS - it stands for Microprocessor without interlocked pipeline stage. it is a kind of RISC architecture and its annual production is higher than that of Intel x386 based microporcessors.well we normally use pipeline to fully utilise the processing resource and meanwhile use interlock to avoid the harzard such as "load to use".but interlock again makes the system waste its precious work cycles. So MIPS design comes to play to compromise these drawback while removing interlock and making changes in micro instructions.

if u dont get something above, just mail me or find on the web. thanks.
ps all things above and next posts are just my thoughts and opnions. i wont be responsible for correctness of above and coming definations and facts.
