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? The speed of clock PIC12F84 is 20 MHz. g) Memory used? RAM 68 bits and rom 64 bits. h) Is it a good choice of up? Yes I think it was good for that application that time because the 8x8 led matrix block useful because we can build led display whit 8 rows and 8 columns.

5 2) The Membership Card. The Membership Card is a reproduction of the original Popular Electronics Elf computer, repackaged to fit in a pocket-sized Altoids(R) tin. 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? RCA 1802 has 16 bit address lines and 8 bit data lines multiplexed. c) Big or Little endian? RCA 1802 was a little endian up. d) RISC or CISC? It was RISC processors. e) Registers in RCA 1802? Its register groups consist of sixteen 16-bit registers. The program counter (PC) can exist in any of those, providing a simple way to implement multiple PCs, pointers, or registers. Of which eight are general purpose registers and some records.
6 f) What type of interrupt structure is available and how many interrupts can be used? On-Chip DMA, Interrupt, and Flag Inputs. g) Speed of the clock? It has maximum clock frequency is 3 Mhz. h) Memory used? The RCA 1802 uses a total ROM and RAM memory of up to 65,536 Bytes. i) Is this a good choice of up for this application? Why? Why not? I think this was a good choice because of it has low clock frequency, low power consumption and readily available radiation hardened version for atmosphere outside the earth.

Designed as a true platform for low power development, it enables designs with sleep currents as low as 20nA. The board is suitable for prototyping many low power applications including RF sensors, data loggers, temperature sensors, electronic door locks, metering sensors, remote controls, security sensors, smart cards, and energy harvesting. The PICtail interface supports Microchip s extensive line of daughter cards for easy evaluation of your next low power application.
8 a) Microprocessor used: PIC24F16 b) Architecture: Modified Harvard Architecture. c) Address and data bus width: It has 24 bit address lines and 16 bit data bus. d) Big or Little Endian? The PIC24F is Little endian processor. e) Is PIC24F RISC or CISC? The PIC24F is a RISC processor. f) Registers in the PIC24F? PIC24F devices have sixteen; 16-bit Working registers in the programmer s model. Each of the Working Registers can act as a data, address or address offset register. g) Speed of the clock? The speed of clock PIC24F start from 8MHz up to 32 MHz h) Memory used? The program memory size is 4KB and the ram size is 512 bytes. i) Is it a good choice of up? Yes I think it was a good choice for the application specified because The board is suitable for prototyping many low power applications including RF sensors, data loggers, temperature sensors, electronic door locks, metering sensors, remote controls, security sensors, smart cards, and energy harvesting j) Number of Interrupts?

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
11 a) Up used: The Texas Instruments MSP430 b) Architecture: c) Address and data bus width: It has 16 bit address bus and 16 bit data bus. d) Big or Little Endian? 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? MSP bit Ultra-Low-Power Microcontroller has 2kB Flash and 256B RAM. i) Is it a good choice of up? 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

Utility companies are starting to deploy electronic metering systems that capture and transmit usage information with the long-term goal to empower and educate users as to the real-time cost and impact of using an appliance at a particular moment in time.

The processor delivers outstanding computational performance and exceptional system response to events while meeting the challenges of low dynamic and static power constraints. The processor is highly configurable enabling a wide range of implementations from those requiring memory protection and powerful trace technology to cost sensitive devices requiring minimal area.
15 64-bit Processor Application: Sony VAIO Fit 15E Laptop: The powerful and full featured VAIO Fit E 15 laptop includes a Full HD touchscreen display, Clear Audio+ technology with a subwoofer and HD web camera.
