resistors • device output is ANDed with signal on bus Frame • start condition (S) – SDA 1→0 transition when SCL = 1 • stop condition (P) – SDA 0→1 transition when SCL = 1 • repeated start (Sr) – start is generated instead of stop • bus state – busy … after S and before next P – free … after P and before next S Masters and Slaves • Master device – controls the SCL – starts and stops data transfer – controls addressing of other devices • Slave device – device…

memory and that is interposed between the processor and main memory. The cache acts as a buffer for recently used memory locations. 1.8 Programmed I/O: The processor issues an I/O command, on behalf of a process, to an I/O module; that process then busy-waits for the operation to be completed before proceeding. Interrupt-driven I/O: The processor issues an I/O command on behalf of a process, continues to execute subsequent instructions, and is interrupted -5- by the I/O module when…

English works; they are a guide to help you understand, not 'rules' to be memorized. The important thing is the language itself. If you are learning about the present perfect continuous, for example, it is helpful to memorize a sentence like We've been waiting here for twenty minutes and to imagine a situation at a bus stop like the one in Unit 16A. The explanation - that the action happens over a period of time lasting up to the present - is designed to help towards an understanding of…

POS/EPS so that it knows that the cancel request has been received and cancellation is in progress. The POS/EPS should then use the ‘Get OPT Status’ command to ascertain when the cancellation is complete. To this end the status is initially set to ‘BUSY CANCELLING’ and to ‘IDLE’ on completion of the Cancel process. It is often useful for the POS/EPS integrator to have a better understanding of what is exactly happening on the device. To this end there follows a list of considerations to…

up the model. 'Since the firm folded,' he said, 'I have a little more time on my hands.' He laughed again, rather strangely. For a moment his face looked almost gentle. 'A little more time.' 'That seems odd,' I said. 'You were always so busy.' 'Too busy perhaps.' He looked at me with a small smile. 'Perhaps I should have been a more attentive father.' I laughed.

solução funciona, mas não é boa (cara chato!): Muito complicado. Difícil de entender e se convencer de que está correto. Código de A é diferente do de B. E se houver mais de dois processos ? Enquanto A está esperando, está consumindo CPU (busy waiting). Pontos importantes: Comportamento muito sutil. Difícil de programar e entender. Como provar que está correto ? Quais os critérios de uma boa solução ? Produtor & Consumidor Produtor gera items continuamente e os coloca no buffer.
