The first addressing +level we will call banks. A bank holds data for one or more sensors. The data +in a bank for a sensor is one or more bytes large. + +The number of bytes is fixed for a given bank, you should always read or write +that many bytes, reading / writing more will fail, the results when writing +less then the number of bytes for a given bank are undetermined. + +See below for all known bank addresses, numbers of sensors in that bank, +number of bytes data per sensor and contents/meaning of those bytes. + +Although both this document and the kernel driver have kept the sensor +terminoligy for the addressing within a bank this is not 100% correct, in +bank 0x24 for example the addressing within the bank selects a PWM output not +a sensor. + +Notice that some banks have both a read and a write address this is how the +uGuru determines if a read from or a write to the bank is taking place, thus +when reading you should always use the read address and when writing the +write address. The write address is always one (1) more then the read address. + + +uGuru ready +----------- + +Before you can read from or write to the uGuru you must first put the uGuru +in "ready" mode. + +To put the uGuru in ready mode first write 0x00 to DATA and then wait for DATA +to hold 0x09, DATA should read 0x09 within 250 read cycles. + +Next CMD _must_ be read and should hold 0xAC, usually CMD will hold 0xAC the +first read but sometimes it takes a while before CMD holds 0xAC and thus it +has to be read a number of times (max 50). + +After reading CMD, DATA should hold 0x08 which means that the uGuru is ready +for input. As above DATA will usually hold 0x08 the first read but not always. +This step can be skipped, but it is undetermined what happens if the uGuru has +not yet reported 0x08 at DATA and you proceed with writing a bank address. + + +Sending bank and sensor addresses to the uGuru +---------------------------------------------- + +First the uGuru must be in "ready" mode as described above, DATA should hold +0x08 indicating that the uGuru wants input, in this case the bank address. + +Next write the bank address to DATA. After the bank address has been written +wait for to DATA to hold 0x08 again indicating that it wants / is ready for +more input (max 250 reads). + +Once DATA holds 0x08 again write the sensor address to CMD. + + +Reading +------- + +First send the bank and sensor addresses as described above. +Then for each byte of data you want to read wait for DATA to hold 0x01 +which indicates that the uGuru is ready to be read (max 250 reads) and once +DATA holds 0x01 read the byte from CMD. + +Once all bytes have been read data will hold 0x09, but there is no reason to +test for this. Notice that the number of bytes is bank address dependent see +above and below. + +After completing a successfull read it is advised to put the uGuru back in +ready mode, so that it is ready for the next read / write cycle.

There is no way of sending zero distance codes--a dummy must be - sent if there are none. (History: a pre 2.0 version of PKZIP would - store blocks with no distance codes, but this was discovered to be - too harsh a criterion.) Valid only for 1.93a. 2.04c does allow - zero distance codes, which is sent as one code of zero bits in - length. - 6. There are up to 286 literal/length codes. Code 256 represents the - end-of-block. Note however that the static length tree defines - 288 codes just to fill out the Huffman codes. Codes 286 and 287 - cannot be used though, since there is no length base or extra bits - defined for them. Similarily, there are up to 30 distance codes. - However, static trees define 32 codes (all 5 bits) to fill out the - Huffman codes, but the last two had better not show up in the data. - 7. Unzip can check dynamic Huffman blocks for complete code sets. - The exception is that a single code would not be complete (see #4). - 8. The five bits following the block type is really the number of - literal codes sent minus 257. - 9. Length codes 8,16,16 are interpreted as 13 length codes of 8 bits - (1+6+6). Therefore, to output three times the length, you output - three codes (1+1+1), whereas to output four times the same length, - you only need two codes (1+3). Hmm. - 10.

Note: length code 284 can represent 227-258, but length code 285 - really is 258. The last length deserves its own, short code - since it gets used a lot in very redundant files. The length - 258 is special since 258 - 3 (the min match length) is 255. - 13. The literal/length and distance code bit lengths are read as a - single stream of lengths.

The state machine is + structured roughly as follows: + + for (;;) switch (state) { + ... + case STATEn: + if (not enough input data or output space to make progress) + return; + ... make progress ... + state = STATEm; + break; + ... + } + + so when inflate() is called again, the same case is attempted again, and + if the appropriate resources are provided, the machine proceeds to the + next state. The NEEDBITS() macro is usually the way the state evaluates + whether it can proceed or should return. NEEDBITS() does the return if + the requested bits are not available. The typical use of the BITS macros + is: + + NEEDBITS(n); + ... do something with BITS(n) ... + DROPBITS(n); + + where NEEDBITS(n) either returns from inflate() if there isn't enough + input left to load n bits into the accumulator, or it continues. BITS(n) + gives the low n bits in the accumulator. When done, DROPBITS(n) drops + the low n bits off the accumulator. INITBITS() clears the accumulator + and sets the number of available bits to zero. BYTEBITS() discards just + enough bits to put the accumulator on a byte boundary. After BYTEBITS() + and a NEEDBITS(8), then BITS(8) would return the next byte in the stream. + + NEEDBITS(n) uses PULLBYTE() to get an available byte of input, or to return + if there is no input available. The decoding of variable length codes uses + PULLBYTE() directly in order to pull just enough bytes to decode the next + code, and no more. + + Some states loop until they get enough input, making sure that enough + state information is maintained to continue the loop where it left off + if NEEDBITS() returns in the loop. For example, want, need, and keep + would all have to actually be part of the saved state in case NEEDBITS() + returns: + + case STATEw: + while (want < need) { + NEEDBITS(n); + keep[want++] = BITS(n); + DROPBITS(n); + } + state = STATEx; + case STATEx: + + As shown above, if the next state is also the next case, then the break + is omitted. + + A state may also return if there is not enough output space available to + complete that state. Those states are copying stored data, writing a + literal byte, and copying a matching string. + + When returning, a "goto inf_leave" is used to update the total counters, + update the check value, and determine whether any progress has been made + during that inflate() call in order to return the proper return code. + Progress is defined as a change in either strm->avail_in or strm->avail_out. + When there is a window, goto inf_leave will update the window with the last + output written. If a goto inf_leave occurs in the middle of decompression + and there is no window currently, goto inf_leave will create one and copy + output to the window for the next call of inflate(). + + In this implementation, the flush parameter of inflate() only affects the + return code (per zlib.h). inflate() always writes as much as possible to + strm->next_out, given the space available and the provided input--the effect + documented in zlib.h of Z_SYNC_FLUSH. Furthermore, inflate() always defers + the allocation of and copying into a sliding window until necessary, which + provides the effect documented in zlib.h for Z_FINISH when the entire input + stream available. So the only thing the flush parameter actually does is: + when flush is set to Z_FINISH, inflate() cannot return Z_OK.

The most common codes are necessarily the - shortest codes, so those codes dominate the decoding time, and hence - the speed.

The time it costs to decode the longer codes is - then traded against the time it takes to make longer tables. - - This results of this trade are in the variables lbits and dbits - below. lbits is the number of bits the first level table for literal/ - length codes can decode in one step, and dbits is the same thing for - the distance codes. Subsequent tables are also less than or equal to - those sizes. These values may be adjusted either when all of the - codes are shorter than that, in which case the longest code length in - bits is used, or when the shortest code is *longer* than the requested - table size, in which case the length of the shortest code in bits is - used. - - There are two different values for the two tables, since they code a - different number of possibilities each. The literal/length table - codes 286 possible values, or in a flat code, a little over eight - bits. The distance table codes 30 possible values, or a little less - than five bits, flat. The optimum values for speed end up being - about one bit more than those, so lbits is 8+1 and dbits is 5+1. - The optimum values may differ though from machine to machine, and - possibly even between compilers.

The framework allows the + * codec to refine the transfer_info items in the + * usable callback, so we can simply remove the + * rates the second instance is not using when it + * actually is in use. + * Maybe we'll need to make the sound busses have + * a 'clock group id' value so the codec can + * determine if the two outputs can be driven at + * the same time.
