UTMC/BOEING - 393-35156-003 – HP56A - IC. RISC Processor, Gold.
IC. RISC Processor, Gold.
A RISC (Reduced Instruction Set Computer) processor is a type of microprocessor designed to execute a smaller set of simple, optimized instructions very quickly, often in a single clock cycle. This design philosophy prioritizes simplicity and efficiency, leading to lower power consumption, reduced chip space, and faster execution for specific tasks. RISC architectures are prevalent in mobile devices like smartphones and tablets, as well as in supercomputers, due to their excellent performance-per-watt.
The term "Utmc hp56a" refers to an early, multi-chip implementation of the 32-bit PA-RISC 1.0 architecture by Hewlett-Packard (HP), most likely the NMOS-III-based NS-1 processor. Specifications for these early PA-RISC processors are scarce, and naming conventions can be confusing.
HP56A processor (NMOS-III NS-1) specifications
• Architecture: The processor used the 32-bit PA-RISC 1.0 architecture with a three-stage pipeline.
• Fabrication: It was one of the first PA-RISC CPUs to be implemented in a multi-chip, single circuit board design using the NMOS-III fabrication process, following an earlier TTL implementation (TS-1).
• Clock speed: The clock speed was typically between 25 and 30 MHz.
• Processor board: The CPU consisted of a single NMOS-III chip supported by external VLSI chips on a single circuit board, or two boards in the case of the HP 9000/825.
• Transistors: The NS-1 chip featured approximately 144,000 transistors.
• Cache: It utilized a large off-chip L1 cache, which was a tradition in many generations of PA-RISC processors. For the NMOS NS-1, the L1 cache ranged from 16 KB to 128 KB.
• Translation Lookaside Buffer (TLB): The processor relied on a massive off-chip TLB with 4,096 entries. This was a notable feature compared to contemporary processors with much smaller on-chip TLBs.
• Memory: The system could address a physical memory space of up to 512 MB.
• System Bus: A System Interface Unit (SIU) connected the CPU to the 64-bit System Main Bus (SMB).
Made by UTMC (United Technologies Microelectronics Center) in USA
Applications: The HP56A reference points to a specific production variant of the processor, potentially used in the HP 9000 Model 825 server from 1987.
