Detailed Description

Parameter RAM wrapper.

This was generalised from ipbus dpram. This ram is 512 bit wide and 5 word deep. All the parameters should fit in one word, and the five words will cover the 5 eta values.

The RAM is also accessed via ipbus in chunks of 32 bits. From ipbus point of view the RAM is 32-bit wide and 64-word deep.

The RAM data format is implemented in IPBusTopAlgoModule.vhd where the signals are connected to the RAM.

The following table represent the RAM data format as seen from ipbus. Only the first 16 words are represented. The following words have the same structure for the greater eta values:

• Words 0 to 7 eta = 0
• Words 8 to 15 eta = 1
• Words 16 to 23 eta = 2
• Words 24 to 31 eta = 3
• Words 32 to 39 eta = 4
