Each item in the interrupt vector table stands for a unique set of information.
6) A DMA controller transfers 32 bit words to memory using cycle stealing. The words are assembled from a device that transmits characters at a rate of 2400 characters per second. Each character is 8 bit length. The CPU is fetching and executing instructions at an average rate of 1 million instructions per second. By how much will the CPU be slowed down because of the DMA transfer?
The outputs of four registers, A, B, C, D, H, L are connected through 8:1 line multiplexer to the input of a fifth register, X. Each register is 16 bits long. The required transfers are dictated by four timing variables, T0 through T3 as follows: T0 : X←A T1 : X←B T2 : X←C T3 : X←D The timing variables are mutually exclusive, which means that only one variable is equal to 1 at any given time, while the others are equal to 0. Draw a block diagram showing the hardware implementation of the register transfers. Include the connections necessary from the four timing variables to the selection inputs of the multiplexers and to the load input of register X.

LAB4 – Using the 8051 Timers in polling mode Overview The purpose of this lab is to control and program the MC8051 Timers of the micro-controller in a given sequence. The program reads port 0 (P0) and outputs its value on port 1 (P1). P0 input is incremented at a controlled rate and displayed on P2. Display update takes place once at the end of a sequence including Timer0 overflow followed by Timer1 overflow. Timer0 and Timer1 are programmed using the polling mode, no interrupts. The status of TF0 and TF1 are displayed on Port 3 bit 0 (P3.0) and bit 1 (P3.1) respectively. Steps First, configure and initialize the required parallel ports; Timer 0 to mode 1, and Timer1 to mode 1. The Main program starts at code memory address 40H, the main program only function is reading P0, updating P1 and P2, and displaying the two overflow flags on port 3 two bits. Second, in the main program configure the two timers, Timer0 and Timer1, for Mode 1 with maximum delay time. Start Timer0, read…
