Abstract
Methods and structures that implement an event counter in a RAM are provided. A method includes providing a count-RAM, a carry-RAM, and a pre-counter corresponding to an event source. A column in the count-RAM and a column in the carry-RAM represent a value of a value of the event counter. The method further includes storing a count of the event counter received via the pre-counter in the count-RAM and the carry-RAM in a transposed, bit-serial format, such that location zero of the count-RAM and the carry-RAM counts the least significant bit (LSB) of the event counter.
