In computer architecture and engineering, a sequencer or microsequencer generates the addresses used to step through the microprogram of a control store.It is used as a part of the control unit of a CPU or as a stand-alone generator for address ranges.
A sequencer is mostly a counter, but usually also has some way to jump to a different part of the control store depending on some data, usually data from the instruction register and always some part of the control store. The simplest sequencer is just a register loaded from a few bits of the control store.
A control store is the part of a CPU's control unit that stores the CPU's microprogram.It is usually accessed by a microsequencer.A control store implementation whose contents are unalterable is known as a Read Only Memory (ROM) or Read Only Storage (ROS); one whose contents are alterable is known as a Writable Control Store (WCS).
The languages used as source code for logic compilers are called hardware description languages, or HDLs. [1] PALASM, ABEL and CUPL are frequently used for low-complexity devices, while Verilog and VHDL are popular higher-level description languages for more complex devices. The more limited ABEL is often used for historical reasons, but for ...
In computers, hardware performance counters (HPC), [1] or hardware counters are a set of special-purpose registers built into modern microprocessors to store the counts of hardware-related activities within computer systems. Advanced users often rely on those counters to conduct low-level performance analysis or tuning.
The Ensoniq Performance Sampler (EPS) was one of the first few affordable samplers on the market. It was manufactured from 1988 to 1991 by Ensoniq in Malvern, Pennsylvania , US. The EPS is a 13-bit sampler and replaced the Mirage - widely regarded as the first truly affordable sampling keyboard.
AMD Am2901: 4-bit-slice ALU. Am2900 is a family of integrated circuits (ICs) created in 1975 by Advanced Micro Devices (AMD). They were constructed with bipolar devices, in a bit-slice topology, and were designed to be used as modular components each representing a different aspect of a computer control unit (CCU).
Single instruction, multiple data. Single instruction, multiple data (SIMD) is a type of parallel processing in Flynn's taxonomy.SIMD can be internal (part of the hardware design) and it can be directly accessible through an instruction set architecture (ISA), but it should not be confused with an ISA.
