SPARCstation SLC
The SPARCstation, SPARCserver and SPARCcenter product lines are a series of SPARC-based computer workstations and servers in desktop, desk side (pedestal) and rack-based form factor configurations, that were developed and sold by Sun Microsystems. The first SPARCstation was the SPARCstation 1 (also known as the Sun 4/60), introduced in 1989. The series was very popular and introduced the Sun-4c architecture, a variant of the Sun-4 architecture previously introduced in the Sun 4/260. Thanks in part to the delay in the development of more modern processors from Motorola, the SPARCstation series was very successful across the entire industry. The last model bearing the SPARCstation name was the SPARCstation 4. The workstation series was replaced by the Sun Ultra series in 1995; the next Sun server generation was the Sun Enterprise line introduced in 1996. Models Desktop and deskside SPARCstations and SPARCservers of the same model number were essentially identical systems, the o ...

SPARCstation 1
The SPARCstation 1 (Sun 4/60, code-named ''Campus'') is the first of the SPARCstation series of SPARC-based computer workstations sold by Sun Microsystems. The design originated in 1987 by a Sun spin-off company, Unisun, which was soon re-acquired. The SPARCstation 1 has a distinctive slim enclosure (a square 3-inch-high "pizza box") and was first sold in April 1989, with Sun's support ending in 1995. Based on a LSI Logic RISC CPU running at 20 MHz, with a Weitek 3170 (or 3172) FPU coprocessor, it was the fourth Sun computer (after the 4/260, 4/110 and 4/280) to use the SPARC architecture and the first of the sun4c architecture. The motherboard offered three SBus slots and had built-in AUI Ethernet, 8 kHz audio, and a 5 MB/s SCSI-1 bus. The basic display ran at 1152×900 in 256 colours, and monitors shipped with the computer were 16 to 19 inch greyscale or colour. Designed for ease of production to compete with high-end PCs or Macs (its principal competitors wer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

SPARCstation 20
The SPARCstation 20 or SS20 (code-named ''Kodiak'') is a discontinued Sun Microsystems workstation introduced in March 1994 based on the SuperSPARC or hyperSPARC CPU. It is one of the last models in the SPARCstation family of Sun "pizza box form factor, pizza box" computers, which was superseded by the Sun Ultra series, UltraSPARC design in 1995. Specifications Release Price Sun rolled out the SPARCstation 20 for .

HyperSPARC
The hyperSPARC, code-named "Pinnacle", is a microprocessor that implements the SPARC Version 8 instruction set architecture (ISA) developed by Ross Technology for Cypress Semiconductor. The hyperSPARC was introduced in 1993, and competed with the Sun Microsystems SuperSPARC. Raju Vegesna was the microarchitect. The hyperSPARC was Sun Microsystem's primary competitor in the mid-1990s. When Fujitsu acquired Ross from Cypress, the hyperSPARC was considered to be more important by its new owner than the SPARC64 developed by HAL Computer Systems, also a Fujitsu subsidiary, a view which was shared with analysts. Description The hyperSPARC was a two-way superscalar microprocessor. It had four execution units: an integer unit, a floating-point unit, a load/store unit and a branch unit. The hyperSPARC has an on-die 8 KB instruction cache, from which two instructions were fetched per cycle and decoded. The decoder could not decode new instructions if the previously decoded instruction ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ross Technology
Ross Technology, Inc. was a semiconductor design and manufacturing company, specializing in SPARC microprocessors. It was founded in Austin, Texas in August 1988 by Dr. Roger D. Ross, a leading computer scientist who headed Motorola's Advanced Microprocessor Division and directed the developments of Motorola's MC68030 and RISC-based 88000 microprocessor families. Dr. Ross was accompanied by Carl Dobbs, Janet Sooch, Steve Goldstein and Travor Smith, who were from Motorola's High-end Microprocessor Division, and were involved in the development of the 88000 microprocessor. He was later was joined by Am29000 engineer Raju Vegesna from AMD, who was originally hired by Dr. Ross at Motorola. Cypress Semiconductor provided initial funding.

Central Processing Unit
A central processing unit (CPU), also called a central processor, main processor or just processor, is the electronic circuitry that executes instructions comprising a computer program. The CPU performs basic arithmetic, logic, controlling, and input/output (I/O) operations specified by the instructions in the program. This contrasts with external components such as main memory and I/O circuitry, and specialized processors such as graphics processing units (GPUs). The form, design, and implementation of CPUs have changed over time, but their fundamental operation remains almost unchanged. Principal components of a CPU include the arithmetic–logic unit (ALU) that performs arithmetic and logic operations, processor registers that supply operands to the ALU and store the results of ALU operations, and a control unit that orchestrates the fetching (from memory), decoding and execution (of instructions) by directing the coordinated operations of the ALU, registers and other co ...

MBus (SPARC)
MBus is a computer bus designed and implemented by Sun Microsystems for communication between high speed computer system components, such as the central processing unit, motherboard and main memory. SBus is used in the same machines to connect add-on cards to the motherboard. MBus was first used in Sun's first multiprocessor SPARC-based system, the SPARCserver 600MP series (launched in 1991), and later found use in the SPARCstation 10 and SPARCstation 20 workstations. The bus permits the integration of several microprocessors on a single motherboard, in a multiprocessing configuration with up to eight CPUs packaged in detachable MBus modules. In practice, the number of processors per MBus is limited to four. Single processor systems were also sold that use the MBus protocol internally, but with the CPUs permanently attached to the motherboard to lower manufacturing costs. MBus specifies a 64-bit datapath, which uses 36-bit physical addressing, giving an address space of 64 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
