ABSTRACT:
A cache unit couples between a main store and data processing unit. The cache unit includes a cache store organized into a plurality of levels, each for storing blocks of information in the form of data and instructions. The cache unit further includes a write command buffer, a transit block buffer and command queue apparatus coupled to the buffers for controlling the sequencing of commands stored in the buffers. The command queue apparatus includes a plurality of multibit storage locations for storing address and control information. The control information is coded to specify the type of command and the number of words the command contains. The address information is used as a pointer for read out of the command from either the write buffer or transit block buffer simplifying control. Control circuits included within the command queue apparatus in accordance with signals corresponding to the control information and use of the address information control the sequencing of commands so as to maximize the use of the buffer storage capacity.
