Computer Evolution and Performance Part 15

Intel Core2Duo
- Further development of the Core Duo.

• Building processor between the first and second.

- Technology denganL2 dual processor cache up to 2MB.
- Do not focus on speed but on the ability of computing resolution two times faster.

History of the Intel Processor


Intel's series 4004 and 8008


Intel's 8080 series, 80286


Intel's 80386 series, 486 and 586


PowerPC
- Project RISC system beginning in 1975 by IBM in the computer mini-series 801.
- Series is the first prototype, a series of commercial PC RT is the introductions in 1986.
- IBM's Year 1990 issue is the next generation of IBM RISC System/6000 which is the engine superskalar RISC workstations.
- After this architecture known as the IBM POWER architecture.
Det: RISC (Reduced Instruction Set Computers)

PowerPC
- IBM formed a partnership with Motorola produced a series microprocessor 6800.
- Apple use Motorola chips in Macintosh. Currently there are 4 groups PowerPC.

PowerPC 6800 series


Group Power PC
- 601, is a 32 bit machine is a massive production for the PowerPC architecture known community.
- 603, is a computer desktop and portable computers. This same group with a 601 series, but cheaper for the purpose of efficient.
- 604 series PowerPC machines for use lowend computer servers and desktop computers.
- 620, intended for the use of high-end servers. Machine with 64 bit architecture.
- 740/750, with a series of L2 cache.
- G4, such as the 750 series but is faster and uses 8 parallel instructions.

Computer Evolution and Performance Part 13

Organization and Architecture Chip
- Increase the speed processor.

• In carried out primarily by reducing the size of "Logic gate."

>> "Gate" more, more meetings, the speed increases.
>> Processing time can be shortened.
- Addition of the cache size and speed.

• It is part of the processor chip.

>> Cache to reduce the access time is significant.
- Changing the organization and processor architecture.

• Improving the effectiveness and speed of execution.

• Processing in parallel.

Intel's Microprocessor Performance


The increase in capacity Cache
- Consists of two or three levels of cache between the processor and main memory.
- The increase in chip density.

• The more cache memory in the chip.

>> Faster access the cache.
- In the Pentium 10% allocated to the cache.
- In the Pentium 4 is allocated 50%.

New Approach - Multiple Cores
- Multiple processors on one chip.

• Large shared cache

- With one processor, proportionate increase performance straight with the increase of complexity.
- If the software can utilize multiple processor, the processor can mean two performance fold.
- So, take two simple processor in the chip better than one processor that is more complex.
- With two processors, cache it bigger.

• Consumption of power in the logical memory is smaller than the logical process.

- Example: IBM POWER4

• Two cores based on the Power PC.
