| | CPU design - Wikipedia, the free encyclopedia |
 | | The computer designs based on this theory were called Reduced Instruction Set Computers, or RISC. | | | Each of the computer designs of the early 1950s was a unique design; there were no upward-compatible machines or computer architectures with multiple, differing implementations. | | | Hence the instruction set was designed to manipulate not just simple binary numbers, but text, scientific floating-point (similar to the numbers used in a calculator), and the binary coded decimal arithmetic needed by accounting systems. |

| | 4.4 Basic CPU Design |
| | The next advance in computer design was the programmable computer system, one that allowed a computer programmer to easily "rewire" the computer system using a sequence of sockets and plug wires. | | | The CPU is attempting to fetch the next byte from the prefetch queue for use as an operand, at the same time it is fetching operand data from the prefetch queue for use as an opcode. | | | When designing an instruction set, the CPU's designers generally choose opcodes that are a multiple of eight bits long so the CPU can easily fetch complete instructions from memory. |

| | CPU design |
| | In modern computer design, the memory is often integrated into the same programmable chip as the CPU, so that a single chip becomes the entire computer (a system known as a SOC, or System On a Chip). | | | The opcodes of a CPU are simply unique binary numbers: A specific number is used for the LDA instruction, while a different number is used for the STA instruction. | | | The CPU needs to be able to act on this opcode and select a course of action based on exactly what that opcode is. This is the job for the instruction decoder, which in Verilog can be programmed quite easily using the case statement. |

| | Dual-CPU Chip Scheme For Network App Melds Two Design Cultures |
| | Rather than trusting critical paths to synthesis,the majority of the CPU was created at the schematic level, and then implemented by a combination of hand design and data path compilation. | | | The combination of very demanding CPU clock rate and complex, block-oriented overall chip architecture made the design of the x2 a hybrid -- demanding QED's deep experience in fast CPU design and techniques from the emerging world of deep-submicron SoC design. | | | Overall, the project represents an interesting blend of the hand-design school of CPU craftsmanship and the hierarchical synthesis approach to modern SoC design. |

| | CPU Design HOW-TO |
| | CPU is the "brain" of computer and is a very vital component of computer system and is like a "cousin brother" of operating system (Linux or Unix). | | | Supercomputers traditionally have been expensive, highly customized designs purchased by a select group of customers, but the industry is being overhauled by comparatively mainstream technologies such as Intel processors, InfiniBand high-speed connections (see also Myricom, and Fibre Channel storage networks that have become fast enough to accomplish many tasks. | | | In contrast to shared memory machines the user must be aware of the location of the data in the local memories and will have to move or distribute these data explicitly when needed. |

| | Great Microprocessors of the Past and Present |
| | A design typical of many load-store processors, the PA-RISC (Precision Architecture, originally code-named Spectrum) was designed to replace older 16-bit stack-based processors in HP-3000 MPE minicomputers, and Motorola 680x0 processors in the HP-9000 HP/UX Unix minicomputers and workstations. | | | Later, Motorola designed a successor called Coldfire (early 1995), in which complex instructions and addressing modes (added to the 68020) were removed and the instruction set was recoded, simplifying it at the expense of compatibility (source only, not binary) with the 680x0 line. | | | The R2000 design came from the Stanford MIPS project, which stood for Microprocessor without Interlocked Pipeline Stages [See Appendix A], and was arguably the first commercial RISC processor (other candidates are the ARM and IBM ROMP used in the IBM PC/RT workstation, which was designed around 1981 but delayed until 1986). |

| | Embedded.com - Will Self-timed Asynchronous Logic Rescue CPU Design? |
| | Although asynchronous designs usually require more transitions on a computational path than synchronously designed CPUs, the transitions usually only occur in areas involved in the current computational task. | | | Bernard Cole is the managing editor for embedded design and net-centric computing at EE Times and the editor of iApplianceweb. | | | Although it is being resisted fiercely as an all-encompassing design methodology, major semiconductor firms such as Intel, TI, IBM, and LSI Logic are selectively making use of asynchronous self-clocking mechanisms in their designs. |

| | Comments for: Intel reveals details of new CPU design - ja.zz |
| | Unlike Intel's current dual-core CPU designs, which don't really share resources or communicate with one another except over the front-side bus, this new design looks to be a much more intentionally multicore design. | | | It is designed to secure your computer against you. | | | This dual-core CPU design will, as we've reported, support an array of Intel technologies, including 64-bit EM64T compatibility, virtualization, enhanced security, and active management capabilities. |

| | .Net Security Blog : A Look at the Xbox 360 CPU Design |
| | This worked well since our opcode design was that each opcode fit into a single byte, so we only ever had to increment by one. | | | Since I have my degree in hardware design, I always find these types of things interesting. | | | I think "Xbox 360 CPU Design" might be a bad link. |
