Abstract
A cache has an array for holding data or instruction values, a buffer connected to the array, and means for accessing the buffer to retrieve a value for a processing unit. The accessing means uses wires having a pitch which is substantially equal to a wire pitch of the cache array. Multiplexers can be used with a plurality of such buffers to create a common output path. The cache can be interleaved, with the array being a first subarray, and the buffer being a first buffer, and further comprising a second subarray and a second buffer, wherein the first and second buffers separate the first and second subarrays. The invention can be applied to a store-back buffer as well as a reload buffer.
