PC bus

PC bus

(1) The data pathway between the CPU and peripherals in a PC. See PC data buses.

(2) The official name of the 8-bit bus architecture used in first-generation IBM PCs and XTs. The PC bus was superseded by the 16-bit AT bus, later known as ISA, which also accepted 8-bit PC bus cards. See ISA bus and PC data buses.

Intel and companies like NVIDIA enjoy a long-standing collaborative relationship with the common goal of driving progress in PC technology, including transitioning the PC industry to an advanced PC bus architecture, PCI Express.
The card fits directly into a PC, occupying a short slot, and takes power from the PC bus. It uses 32-bit floating-point DSP, operates at 50 MHz, supports position capture times of 200 nsec, and accepts encoder signals to 7.5 MHz.
The PC Bus is currently unable to make efficient use of Gigabit speeds because it only operates at 1 Gbps itself, and all PC peripherals use it to communicate with each other (i.e., processor, NIC, memory, hard drive, etc).
