Instructions per second. Instructions per second ( IPS) is a measure of a computer 's processor speed. For complex instruction set computers (CISCs), different instructions take different amounts of time, so the value measured depends on the instruction mix; even for comparing processors in the same family the IPS measurement can be problematic.

1990s. The 32-bit microprocessor dominated the consumer market in the 1990s. Processor clock speeds increased by more than tenfold between 1990 and 1999, and 64-bit processors began to emerge later in the decade. In the 1990s, microprocessors no longer used the same clock speed for the processor and the RAM.
Instruction cycle. The instruction cycle (also known as the fetch–decode–execute cycle, or simply the fetch-execute cycle) is the cycle that the central processing unit (CPU) follows from boot-up until the computer has shut down in order to process instructions. It is composed of three main stages: the fetch stage, the decode stage, and the ...
In computer engineering, instruction pipelining is a technique for implementing instruction-level parallelism within a single processor. Pipelining attempts to keep every part of the processor busy with some instruction by dividing incoming instructions into a series of sequential steps (the eponymous "pipeline") performed by different processor units with different parts of instructions ...
Computer architecture. Block diagram of a basic computer with uniprocessor CPU. Black lines indicate control flow, whereas red lines indicate data flow. Arrows indicate the direction of flow. In computer science and computer engineering, computer architecture is a description of the structure of a computer system made from component parts. [ 1]
I/O Memory: 2 MB EDO DRAM. CPU Core: Original PlayStation CPU (MIPS R3000A clocked at 33.8688 MHz or 36.864 MHz+PS1 GTE and MDEC for backwards compatibility with PS1 games) Automatically underclocked to 33.8688 MHz to achieve hardware backwards compatibility with original PlayStation format games. Sub Bus: 32-bit.
To keep costs low on high-volume competitive products, the CPU core is usually bundled into a system-on-chip (SOC) integrated circuit. SOCs contain the processor core, cache and the processor's local data on-chip, along with clocking, timers, memory (SDRAM), peripheral (network, serial I/O), and bus (PCI, PCI-X, ROM/Flash bus, I2C) controllers.
