The 8052 was an enhanced version of the original 8051 that featured 256 bytes of internal RAM instead of 128 bytes, 8 KB of ROM instead of 4 KB, and a third 16-bit timer. Most modern 8051-compatible microcontrollers include these features. The 8032 had these same features as the 8052 except it lacked internal ROM program memory.
A prescaler is an electronic counting circuit used to reduce a high frequency electrical signal to a lower frequency by integer division.The prescaler takes the basic timer clock frequency (which may be the CPU clock frequency or may be some higher or lower frequency) and divides it by some value before feeding it to the timer, according to how the prescaler register(s) are configured.
Depending on the processor architecture, this can include, but is not limited to: I/O and peripheral control (such as serial ports or general-purpose IOs) timers; stack pointer; stack limit (to prevent overflows) program counter; subroutine return address; processor status (servicing an interrupt, running in protected mode, etc.)
CPU time (or process time) is the amount of time that a central processing unit (CPU) was used for processing instructions of a computer program or operating system. CPU time is measured in clock ticks or seconds. Sometimes it is useful to convert CPU time into a percentage of the CPU capacity, giving the CPU usage.
Tasword is a word processor for microcomputers developed by Tasman Software. [1] The first version was released for the ZX81 in 1982 and spawned two major revisions in addition to several add-ons and, later, tailored versions for the +2 and +3 Spectrum models, the SAM Coupé, [2] the MSX, [3] the Timex Sinclair 2068 [4] and the Amstrad CPC [5] range.
MCU 8051 IDE is a free software integrated development environment for microcontrollers based on the 8051. MCU 8051 IDE has a built-in simulator not only for the MCU itself, but also LCD displays and simple LED outputs as well as button inputs.
In computer architecture, cycles per instruction (aka clock cycles per instruction, clocks per instruction, or CPI) is one aspect of a processor's performance: the average number of clock cycles per instruction for a program or program fragment. [1] It is the multiplicative inverse of instructions per cycle.
Registers are normally measured by the number of bits they can hold, for example, an 8-bit register, 32-bit register, 64-bit register, 128-bit register, or more.In some instruction sets, the registers can operate in various modes, breaking down their storage memory into smaller parts (32-bit into four 8-bit ones, for instance) to which multiple data (vector, or one-dimensional array of data ...
