: Provides a detailed summary of the Am2930, noting its 16-level subroutine stack , relative addressing capability, and ability to execute 32 microinstructions .
The is a 4-bit slice Program Control Unit (PCU) produced by Advanced Micro Devices (AMD) as part of their 2900 series of microprogrammable bipolar devices. It is designed to handle program control functions, such as address sequencing and subroutine management, in high-performance microprogrammed systems. AM2930.rar
