ABSTRACT:
A system for instruction memory storage and processing in a computing device having a processor, the system is based on backwards branch control information and comprises a dynamic loop buffer (DLB) which is a tagless array of data organized as a direct-mapped structure; a DLB controller having a primary memory unit partitioned into a plurality of banks for controlling the state of the instruction memory system and accepting a program counter address as an input, the DLB controller outputs distinct signals. The system further comprises an address register located in the memory of the computing device, it is a staging register for the program counter address and an instruction fetch process that takes two cycles of the processor clock; and a bank select unit for serving as a program counter address decoder to accept the program counter address and to output a bank enable signal for selecting a bank in a primary memory unit, and a decoded address for access within the selected bank.
