PIC means "Priority Interrupt Controller" - a chip by Intel named 8259 in the PC/XT and 8259-2 in the PC/AT. Later they integrated it into the south bridge of the chipset, and added an APIC - "Advanced Priority Interrupt Controller" which allows many more interrupt request lines (224) than that of the original PC/XT (8) and PC/AT (15).
