The dynamic power (switching power) dissipated by a chip is C·V 2 ·A·f, where C is the capacitance being switched per clock cycle, V is voltage, A is the Activity Factor [1] indicating the average number of switching events per clock cycle by the transistors in the chip (as a unitless quantity) and f is the clock frequency.
The TMS34010 is a bit addressable, 32-bit processor, with two register files, each with fifteen registers and sharing a sixteenth stack pointer. [6] The instruction set supports drawing into two-dimensional bitmaps, arbitrary variable-width data, conversion of pixel data to different bit depths, and arithmetic operations on pixels.
The High-Performance Graphics Display Controller 7220 (commonly μPD7220 or NEC 7220) is a video display controller and a Graphics processing unit, capable of drawing lines, circles, arcs, and character graphics to a bit-mapped display.
Compared to the unified system and video memory used by other 8-bit computers of the time, such as the Apple II, ZX Spectrum, and Commodore 64, separate memory has the advantage of freeing up of the Z80 processor's 64 KiB address space for main RAM, and the VDP does not need to steal CPU cycles to access video memory.
The CPU communicates with the VDP through an 8-bit bus. A pin controlled by the CPU separates this bus into two "ports", a control port and a data port. To write or read a byte of video memory, the CPU first has to write two bytes on the VDP's control port to the VDC's internal address register. Next, the CPU performs the actual write or read ...
Paul Finebaum has been talking about college football — mostly the Southeastern Conference — for decades.. He doesn't like how the new 12-team College Football Playoff is shaping up. His ...
For example, an IBM PC with an Intel 80486 CPU running at 50 MHz will be about twice as fast (internally only) as one with the same CPU and memory running at 25 MHz, while the same will not be true for MIPS R4000 running at the same clock rate as the two are different processors that implement different architectures and microarchitectures ...
