Abstract
A method and system thereof for managing a computer system memory, where the memory is structured as contiguous memory chunks, each chunk having a header. A chunk header includes a first offset value, a sign bit associated with the first offset value, and a number of bits having values that are added to a second offset value that is determined from the first offset value. The second offset value is then used for determining an actual offset value that is applied to a base address to provide a memory location of the memory chunk. In one such embodiment, the first offset value includes 23 bits (plus the sign bit), the number of bits added to the second offset value is two, and the actual offset value includes 27 bits (plus the sign bit). As such, up to 128 MB of memory can be addressed.
