2 8-Bit Processor Application. 1) Matrix LED Display Software When we need to drive 64 individual LEDs you would need 64 individual output pins. Each led connected to a output pin on one side and ground on the other. In fact, Multiplexing uses to reduce the number of pins needed to drive an LED display. You can do this by splitting the 64 led display into 8 rows and 8 columns which lets you drive it using 8 row outputs and 8 column outputs. In fact the 8x8 led matrix block useful because we can build led display whit 8 rows and 8 columns. in this project we are using as PIC16F84x processor type of 8-bit, Johnson Counter, and led display matrix 8x8 LEDs.

3 a) Microprocessor used: PIC16F84 b) Address and data bus width: It has 16 bit address lines and 8 bit data bus. c) Big or Little Endian? The PIC16F84 is Little endian processor. d) Is PIC16F84 RISC or CISC? The PIC16F84 is a RISC processor. e) Registers in the PIC16F84? The pic16f84 CPU also contains a W, INDF, TMR0, PCL, STATUS, FSR, PORTA(4), PORTB(5), EEDATA, EEADR, PCLATH, INTCON, INDF, OPTION_REG, PCL, STATUS, FSR, TRISA, TRISB, EECON1, EECON2, PCLATH, INTCON registers. f) Speed of the clock?

It uses no custom parts, no surface mount assembly, no need for PCs, no megabyte compilers, or secret software to use it. In this project they use CPU as RCA CDP1802ACE microprocessor, up to 32k bytes of memory, 22 bits of I/O, and the needed clock, reset and power supply circuits, and a supercapacitor to maintain memory contents without power. However, the CUP 1802ACE is a good chose because it has low power and low clock frequency. a) Microprocessor used? CPU: RCA CDP1802ACE microprocessor b) What address and data bus width?

10 2)Temperature Recorder With ez430-f2013 Measuring Temperature Plugging a modified MSP-EZ430D board, the size of a quarter, into a LiON battery flashes the green LED three times over 40 seconds letting you know the battery is good and the part is working. Then it begins writing the temperature to FLASH. Put the battery and microprocessor in a draft-free container like a pill holder, with the starting time and date. FLASH memory holds 281, run-length encoded records with a byte counter for the 8.02 seconds time intervals. Unlikely, it could be filled in 38 minutes to a maximum of 6.5 days. One office test ran 4 days and still had free FLASH remaining. Reporting Time-Temperature Using a spreadsheet, load the comma separated values from the Terminal I/O log file. Every pair of lines has an interval counter and the same temperature. The time counter is how many 8.02 second timer intervals for that temperature. For example: 1. 0, , , ,768

MSP430 uses Little Endian ordering format. e) Is MSP430 RISC or CISC? MSP430 is RISC CPU f) Registers in the MSP430? The MSP430 has Sixteen registers are located inside the CPU, providing reduced instruction execution time. This reduces a register-register operation execution time to one cycle of the processor frequency. Four of the registers are reserved for special use as a program counter, a stack pointer, a status register and a constant generator. The remaining registers are available as general purpose registers. g) Speed of the clock? Single Common 32 khz Crystal, Internal System Clock up to 3.8 MHz h) Memory used?

I think it was useful for the application of because Office temperature is often a source of contention. After a complaint is made, it may take hours for someone to show up and by then, the temperature has changed. But traditional temperature recorders are expensive and rare. The Texas Instruments (TI) MSP430F2013 in the ez430-f2013 development kit can work as a low cost ($20) temperature recorder. Item Processor Architecture Description The Texas Instruments MSP430 MIPS
